Python Random Number Generator – A Step by Step Guide

A random number is the outcome of a process which arbitrarily chooses it from a sequence. It is called random number generation. With Python random module, we can generate random numbers to fulfill different programming needs. It has a no. of functions like randint(), random(), choice(), uniform() that as a programmer we can decide to use depending on the use case.

At the core, Python uses a Mersenne Twister algorithm, a pseudo-random generator (PRNG) to generate pseudo-random numbers. Its ability to produce uniform results makes it suitable for many applications. Knowing this fact is essential as it would help us determine when to use it and where not.

Studies reveal that PRNGs are suitable for applications such as simulation and modeling but not recommended for cryptographic purposes. And the same rule applies for the Python random number generator. However, we can use it for programming tasks like generating random integers between a range, randomly select an item from a list or shuffle a sequence in place.

Let’s now check out how to use the Python Random Module and see different functions to generate random numbers.

The Python Random module provides a range of functions to generate random numbers. So the first thing you should be doing is that import this module in your Python script.

import random

Or, you can also try the following syntax.

import random

Next, let’s see what you need to do for using the random module.

import random

Whenever you run the above piece of code, it’ll give you different output. Below is the one that we saw after executing at our end.

import random

Now, you should note the following points from the above example:

  • The code is calling the random() which is the most obvious function for random number generation.
  • It is one of the pre-requisites for most of the methods in the Random module.
  • By default, the random() function generates a float number between 0.0 and 1.0.

Now, we have divided the random number generation into three categories. Each category has some functions to produce desired random values in Python. Let’s check out.

Generate a random number from a range


It will produce a random integer value less than the value specified by the [stop] argument.

If “r” is a random number, then its value will lie in the range 0 <= r < stop.

import random

You can’t pass zero or negative value or a floating point number to this function as it’ll throw the ValueError exception.

Please see the below example.

import random


import random

randrange(start, stop [, step])

It uses the following range [start, stop-1] to return a uniquely selected integer value. If the [step] is specified, then the randrange() output is incremented by it.

If “r” is a random number, then its value will lie in the range start <= r < stop.

import random


import random


import random

random.randint(low, high)

The randint() function is one of many methods that handle random numbers. It has two parameters low and high and generates an integer between low and high (including both).


import random


import random

Choose a random value from a sequence


The choice() function arbitrarily determines an element from the given sequence.

Note– A sequence in Python is the generic term for an ordered set like a list, tuple, etc.


import random


The shuffle() function rearranges the items of a list in place so that they occur in a random order.

For shuffling, it uses the Fisher-Yates algorithm which has O(n) complexity. It starts by iterating the last element in the array to the first entry, then swap each entry with a value at a random index below it.


import random


import random

random.sample(collection, random list length)

The sample() function randomly selects N items from a given collection (list, tuple, string, dictionary, set) and returns them as a list.

It works by sampling the items without replacement. It means a single element from the sequence can appear in the resultant list at most once.


import random


import random

Generate a floating point random number


It selects the next random floating point number from the range [0.0, 1.0]. It is a semi-open range as the random function will always return a decimal value which is less than its upper bound. However, it may return 0.


import random


import random


The seed() function performs the initialization of the pseudorandom number generator (PRNG) in Python.

It sets up the seed value which acts as a base to produce a random number. If you don’t provide a seed value, then Python uses the system current time internally.


import random


import random

random.uniform(lower, upper)

It is an extension of the random() function. In this, you can specify the lower and upper bounds to generate a random number other than the ones between 0 and 1.


import random


import random


import random


import random

random.triangular(low, high, mode)

This function generates a float type random number FRN satisfying the below condition:

import random

Please note a few points before calling the triangular() method.

  • If you don’t specify any of low, high, and mode, then Python takes their values as ZERO, ONE, and the median of the first two values for the MODE.
  • It basically does a symmetric distribution.


import random


import random

How to generate a secure random number?

We have said at the beginning of this tutorial that PRNGs are not secure by default. So, it is a question mark so far that how do we generate a crypto-safe random number.

A crypto-safe random number is an ideal candidate for cryptographic applications. The data integrity remains critical in such software.

There are three ways in Python to generate a secure random value:

Python 3.6 secrets module

First, Python 3.6 introduced a module namely Secrets. It defines functions that can produce cryptographically secure random output. They act under the following conditions:

  • The secrets module has methods that generate a sequence of bytes instead of a single integer/float value.
  • The output quality will vary depending on the OS of the target machine.

Also, note that the secrets module is available from Python 3.6 not in the below versions.


import random


import random

SystemRandom() class random() method

The second method is to call the SystemRandom() class’s random() method.


import random


import random

Directly call the os.urandom()

Finally, you can directly call the os.urandom() method. The SystemRandom() class also uses this approach internally.

It returns a byte string of the specified size useful for the cryptographic purpose.


import random


import random

Convert random bytes into a number

Two of the above methods provide random bytes instead of an integer value. We can use the binascii module to convert the binary output into an integer value.

Check the below example.


import random


import random

In the above case, we used the hexlify() function which converts the bytes into an actual random number output. Also, you would have noted that we ran two iterations to show that each gives a different value.

One more point, the above code uses “iter” as a global variable to distinguish between two calls to the main(). Hope, you knew the below fact.

Note: Global variables in Python are accessible without declaring as global. But it is mandatory to do so for changing their values.

State of random number generator in Python

The random module includes the following two functions to manage the state of the random number generator. Once the state is available, you can use it to reproduce the same random value.


It returns an object carrying the current state of the random generator. You can call the setstate() method with this value to restore the state at any point in time.

Note: By resetting the state, you force the generators to give the same random number again. You should exercise this feature only when needed.


It resets the current state of the generator to the input state object. You can fetch the same by calling the random.getstate() function.

How to call getstate()/setstate()

If you save the last state and reset it, then it is possible to regenerate the same random number. However, if you change any of the random functions or their parameters, then it will break the logic.

Check out the below sampling example and see how the get/set methods impact the random number generation.

import random


import random

It is clear from the summary that resetting the state makes the generator return the same sample list in consecutive attempts.

Using NumPy for random number arrays

NumPy is a scientific computing module in Python. It provides functions to generate multi-dimension arrays.

Since this module isn’t available in Python by default, so you need to pip it first by running:

import random

Get a random multi-dimension array of integers

  • Call random.random_integers(start, stop, size) to generate a 1-d array of random integer numbers between a range
  • Call random.random_integers(start, stop, size=(x, y)) to generate a n-d array of random values between [start, stop]


import random

Choose a random value from a sequence

The numpy module provides the random.choice() method for choosing a random number from the sample list. We can utilize it to select one or more random values from a multi-dimension array.


import random


import random

To learn more variations on randomization using NumPy, check out this post: Generate Floating Point Random Numbers

It covers how you can generate a floating point random number as well as the array of floats using NumPy.

How to generate a universal random number

What is UUID?

A UUID (Universal Unique Identifier) is a 128-bit long number assigned to an object or entity for unique identification. As per specifications, it is quite unlikely that you can regenerate the same UUID.

Python UUID module

Python has a built-in UUID module which generates immutable UUID (Universally Unique Identifier) objects.

All functions in the UUID module are compatible with the available versions of UUID. If you like to generate a cryptographically secure random UUID, then uuid.uuid4() is the recommended function.

Why use UUID?

With the help of a unique identifier, it is easy to locate a specific document or user or resources or any information in a database or computer system.


import random


import random

Exercise – Guess the number game using random module

Dear all, you would have come to the end of this Python random generation guide. Hence, now is the time to test what you have learned from this tutorial.

Your exercise here is to code a famous ‘Guess the Number’ game by using a function from the Python random module.

We are providing our implementation of this game. We used the random.randint(start, stop) to generate a random answer.


The logic is pretty simple.

  • First, you generate a random answer from a specified range by calling a method from the Random module.
  • You also set the max number of attempts for the user to limit the retries.
  • Run a loop, ask the user to enter his choice, count his attempts.
  • Test the input value, if it matches, then stops and greet the user.
  • Otherwise, increment the attempts, let the user try until he exceeds the max tries.
  • If the user fails to guess the right number, then exit from the loop and display the sorry message.

Sample code

import random


There are two outcomes of the ‘Guess the Numer’ game.

Success – You guessed the right number. Here, the less are your retakes, the better you performed.

import random

Failure – You couldn’t guess and exceeded the max attempts.

import random

Summary – Generate Random Numbers in Python

We’ve tried to portray the use of the Python random module and its functions in a simplified manner. Our purpose was to make it utterly simple so that even a newbie could understand it easily.

In this tutorial, we covered the most commonly used Python functions to generate random numbers. However, the Python random module also provides methods for advanced random distributions. These include Exponential, Gamma, Gauss, Lognormal, and Pareto distributions.

What's Python IDLE? How to use Python IDLE to interact with Python?

What's Python IDLE? How to use Python IDLE to interact with Python?

In this tutorial, you’ll learn all the basics of using **IDLE** to write Python programs. You'll know what Python IDLE is and how you can use it to interact with Python directly. You’ve also learned how to work with Python files and customize Python IDLE to your liking.

In this tutorial, you'll learn how to use the development environment included with your Python installation. Python IDLE is a small program that packs a big punch! You'll learn how to use Python IDLE to interact with Python directly, work with Python files, and improve your development workflow.

If you’ve recently downloaded Python onto your computer, then you may have noticed a new program on your machine called IDLE. You might be wondering, “What is this program doing on my computer? I didn’t download that!” While you may not have downloaded this program on your own, IDLE comes bundled with every Python installation. It’s there to help you get started with the language right out of the box. In this tutorial, you’ll learn how to work in Python IDLE and a few cool tricks you can use on your Python journey!

In this tutorial, you’ll learn:

  • What Python IDLE is
  • How to interact with Python directly using IDLE
  • How to edit, execute, and debug Python files with IDLE
  • How to customize Python IDLE to your liking

What Is Python IDLE?

Every Python installation comes with an Integrated Development and Learning Environment, which you’ll see shortened to IDLE or even IDE. These are a class of applications that help you write code more efficiently. While there are many IDEs for you to choose from, Python IDLE is very bare-bones, which makes it the perfect tool for a beginning programmer.

Python IDLE comes included in Python installations on Windows and Mac. If you’re a Linux user, then you should be able to find and download Python IDLE using your package manager. Once you’ve installed it, you can then use Python IDLE as an interactive interpreter or as a file editor.

An Interactive Interpreter

The best place to experiment with Python code is in the interactive interpreter, otherwise known as a shell. The shell is a basic Read-Eval-Print Loop (REPL). It reads a Python statement, evaluates the result of that statement, and then prints the result on the screen. Then, it loops back to read the next statement.

The Python shell is an excellent place to experiment with small code snippets. You can access it through the terminal or command line app on your machine. You can simplify your workflow with Python IDLE, which will immediately start a Python shell when you open it.

A File Editor

Every programmer needs to be able to edit and save text files. Python programs are files with the .py extension that contain lines of Python code. Python IDLE gives you the ability to create and edit these files with ease.

Python IDLE also provides several useful features that you’ll see in professional IDEs, like basic syntax highlighting, code completion, and auto-indentation. Professional IDEs are more robust pieces of software and they have a steep learning curve. If you’re just beginning your Python programming journey, then Python IDLE is a great alternative!

How to Use the Python IDLE Shell

The shell is the default mode of operation for Python IDLE. When you click on the icon to open the program, the shell is the first thing that you see:

This is a blank Python interpreter window. You can use it to start interacting with Python immediately. You can test it out with a short line of code:

Here, you used print() to output the string "Hello, from IDLE!" to your screen. This is the most basic way to interact with Python IDLE. You type in commands one at a time and Python responds with the result of each command.

Next, take a look at the menu bar. You’ll see a few options for using the shell:

You can restart the shell from this menu. If you select that option, then you’ll clear the state of the shell. It will act as though you’ve started a fresh instance of Python IDLE. The shell will forget about everything from its previous state:

In the image above, you first declare a variable, x = 5. When you call print(x), the shell shows the correct output, which is the number 5. However, when you restart the shell and try to call print(x) again, you can see that the shell prints a traceback. This is an error message that says the variable x is not defined. The shell has forgotten about everything that came before it was restarted.

You can also interrupt the execution of the shell from this menu. This will stop any program or statement that’s running in the shell at the time of interruption. Take a look at what happens when you send a keyboard interrupt to the shell:

A KeyboardInterrupt error message is displayed in red text at the bottom of your window. The program received the interrupt and has stopped executing.

How to Work With Python Files

Python IDLE offers a full-fledged file editor, which gives you the ability to write and execute Python programs from within this program. The built-in file editor also includes several features, like code completion and automatic indentation, that will speed up your coding workflow. First, let’s take a look at how to write and execute programs in Python IDLE.

Opening a File

To start a new Python file, select File → New File from the menu bar. This will open a blank file in the editor, like this:

From this window, you can write a brand new Python file. You can also open an existing Python file by selecting File → Open… in the menu bar. This will bring up your operating system’s file browser. Then, you can find the Python file you want to open.

If you’re interested in reading the source code for a Python module, then you can select File → Path Browser. This will let you view the modules that Python IDLE can see. When you double click on one, the file editor will open up and you’ll be able to read it.

The content of this window will be the same as the paths that are returned when you call sys.path. If you know the name of a specific module you want to view, then you can select File → Module Browser and type in the name of the module in the box that appears.

Editing a File

Once you’ve opened a file in Python IDLE, you can then make changes to it. When you’re ready to edit a file, you’ll see something like this:

The contents of your file are displayed in the open window. The bar along the top of the window contains three pieces of important information:

  1. The name of the file that you’re editing
  2. The full path to the folder where you can find this file on your computer
  3. The version of Python that IDLE is using

In the image above, you’re editing the file, which is located in the Documents folder. The Python version is 3.7.1, which you can see in parentheses.

There are also two numbers in the bottom right corner of the window:

  1. Ln: shows the line number that your cursor is on.
  2. Col: shows the column number that your cursor is on.

It’s useful to see these numbers so that you can find errors more quickly. They also help you make sure that you’re staying within a certain line width.

There are a few visual cues in this window that will help you remember to save your work. If you look closely, then you’ll see that Python IDLE uses asterisks to let you know that your file has unsaved changes:

The file name shown in the top of the IDLE window is surrounded by asterisks. This means that there are unsaved changes in your editor. You can save these changes with your system’s standard keyboard shortcut, or you can select File → Save from the menu bar. Make sure that you save your file with the .py extension so that syntax highlighting will be enabled.

Executing a File

When you want to execute a file that you’ve created in IDLE, you should first make sure that it’s saved. Remember, you can see if your file is properly saved by looking for asterisks around the filename at the top of the file editor window. Don’t worry if you forget, though! Python IDLE will remind you to save whenever you attempt to execute an unsaved file.

To execute a file in IDLE, simply press the F5 key on your keyboard. You can also select Run → Run Module from the menu bar. Either option will restart the Python interpreter and then run the code that you’ve written with a fresh interpreter. The process is the same as when you run python3 -i [filename] in your terminal.

When your code is done executing, the interpreter will know everything about your code, including any global variables, functions, and classes. This makes Python IDLE a great place to inspect your data if something goes wrong. If you ever need to interrupt the execution of your program, then you can press Ctrl+C in the interpreter that’s running your code.

How to Improve Your Workflow

Now that you’ve seen how to write, edit, and execute files in Python IDLE, it’s time to speed up your workflow! The Python IDLE editor offers a few features that you’ll see in most professional IDEs to help you code faster. These features include automatic indentation, code completion and call tips, and code context.

Automatic Indentation

IDLE will automatically indent your code when it needs to start a new block. This usually happens after you type a colon (:). When you hit the enter key after the colon, your cursor will automatically move over a certain number of spaces and begin a new code block.

You can configure how many spaces the cursor will move in the settings, but the default is the standard four spaces. The developers of Python agreed on a standard style for well-written Python code, and this includes rules on indentation, whitespace, and more. This standard style was formalized and is now known as PEP 8. To learn more about it, check out How to Write Beautiful Python Code With PEP 8.

Code Completion and Call Tips

When you’re writing code for a large project or a complicated problem, you can spend a lot of time just typing out all of the code you need. Code completion helps you save typing time by trying to finish your code for you. Python IDLE has basic code completion functionality. It can only autocomplete the names of functions and classes. To use autocompletion in the editor, just press the tab key after a sequence of text.

Python IDLE will also provide call tips. A call tip is like a hint for a certain part of your code to help you remember what that element needs. After you type the left parenthesis to begin a function call, a call tip will appear if you don’t type anything for a few seconds. For example, if you can’t quite remember how to append to a list, then you can pause after the opening parenthesis to bring up the call tip:

The call tip will display as a popup note, reminding you how to append to a list. Call tips like these provide useful information as you’re writing code.

Code Context

The code context functionality is a neat feature of the Python IDLE file editor. It will show you the scope of a function, class, loop, or other construct. This is particularly useful when you’re scrolling through a lengthy file and need to keep track of where you are while reviewing code in the editor.

To turn it on, select Options → Code Context in the menu bar. You’ll see a gray bar appear at the top of the editor window:

As you scroll down through your code, the context that contains each line of code will stay inside of this gray bar. This means that the print() functions you see in the image above are a part of a main function. When you reach a line that’s outside the scope of this function, the bar will disappear.

How to Debug in IDLE

A bug is an unexpected problem in your program. They can appear in many forms, and some are more difficult to fix than others. Some bugs are tricky enough that you won’t be able to catch them by just reading through your program. Luckily, Python IDLE provides some basic tools that will help you debug your programs with ease!

Interpreter DEBUG Mode

If you want to run your code with the built-in debugger, then you’ll need to turn this feature on. To do so, select Debug → Debugger from the Python IDLE menu bar. In the interpreter, you should see [DEBUG ON] appear just before the prompt (>>>), which means the interpreter is ready and waiting.

When you execute your Python file, the debugger window will appear:

In this window, you can inspect the values of your local and global variables as your code executes. This gives you insight into how your data is being manipulated as your code runs.

You can also click the following buttons to move through your code:

  • Go: Press this to advance execution to the next breakpoint. You’ll learn about these in the next section.
  • Step: Press this to execute the current line and go to the next one.
  • Over: If the current line of code contains a function call, then press this to step over that function. In other words, execute that function and go to the next line, but don’t pause while executing the function (unless there is a breakpoint).
  • Out: If the current line of code is in a function, then press this to step out of this function. In other words, continue the execution of this function until you return from it.

Be careful, because there is no reverse button! You can only step forward in time through your program’s execution.

You’ll also see four checkboxes in the debug window:

  1. Globals: your program’s global information
  2. Locals: your program’s local information during execution
  3. Stack: the functions that run during execution
  4. Source: your file in the IDLE editor

When you select one of these, you’ll see the relevant information in your debug window.


A breakpoint is a line of code that you’ve identified as a place where the interpreter should pause while running your code. They will only work when DEBUG mode is turned on, so make sure that you’ve done that first.

To set a breakpoint, right-click on the line of code that you wish to pause. This will highlight the line of code in yellow as a visual indication of a set breakpoint. You can set as many breakpoints in your code as you like. To undo a breakpoint, right-click the same line again and select Clear Breakpoint.

Once you’ve set your breakpoints and turned on DEBUG mode, you can run your code as you would normally. The debugger window will pop up, and you can start stepping through your code manually.

Errors and Exceptions

When you see an error reported to you in the interpreter, Python IDLE lets you jump right to the offending file or line from the menu bar. All you have to do is highlight the reported line number or file name with your cursor and select Debug → Go to file/line from the menu bar. This is will open up the offending file and take you to the line that contains the error. This feature works regardless of whether or not DEBUG mode is turned on.

Python IDLE also provides a tool called a stack viewer. You can access it under the Debug option in the menu bar. This tool will show you the traceback of an error as it appears on the stack of the last error or exception that Python IDLE encountered while running your code. When an unexpected or interesting error occurs, you might find it helpful to take a look at the stack. Otherwise, this feature can be difficult to parse and likely won’t be useful to you unless you’re writing very complicated code.

How to Customize Python IDLE

There are many ways that you can give Python IDLE a visual style that suits you. The default look and feel is based on the colors in the Python logo. If you don’t like how anything looks, then you can almost always change it.

To access the customization window, select Options → Configure IDLE from the menu bar. To preview the result of a change you want to make, press Apply. When you’re done customizing Python IDLE, press OK to save all of your changes. If you don’t want to save your changes, then simply press Cancel.

There are 5 areas of Python IDLE that you can customize:

  1. Fonts/Tabs
  2. Highlights
  3. Keys
  4. General
  5. Extensions

Let’s take a look at each of them now.


The first tab allows you to change things like font color, font size, and font style. You can change the font to almost any style you like, depending on what’s available for your operating system. The font settings window looks like this:

You can use the scrolling window to select which font you prefer. (I recommend you select a fixed-width font like Courier New.) Pick a font size that’s large enough for you to see well. You can also click the checkbox next to Bold to toggle whether or not all text appears in bold.

This window will also let you change how many spaces are used for each indentation level. By default, this will be set to the PEP 8 standard of four spaces. You can change this to make the width of your code more or less spread out to your liking.


The second customization tab will let you change highlights. Syntax highlighting is an important feature of any IDE that highlights the syntax of the language that you’re working in. This helps you visually distinguish between the different Python constructs and the data used in your code.

Python IDLE allows you to fully customize the appearance of your Python code. It comes pre-installed with three different highlight themes:

  1. IDLE Day
  2. IDLE Night
  3. IDLE New

You can select from these pre-installed themes or create your own custom theme right in this window:

Unfortunately, IDLE does not allow you to install custom themes from a file. You have to create customs theme from this window. To do so, you can simply start changing the colors for different items. Select an item, and then press Choose color for. You’ll be brought to a color picker, where you can select the exact color that you want to use.

You’ll then be prompted to save this theme as a new custom theme, and you can enter a name of your choosing. You can then continue changing the colors of different items if you’d like. Remember to press Apply to see your changes in action!


The third customization tab lets you map different key presses to actions, also known as keyboard shortcuts. These are a vital component of your productivity whenever you use an IDE. You can either come up with your own keyboard shortcuts, or you can use the ones that come with IDLE. The pre-installed shortcuts are a good place to start:

The keyboard shortcuts are listed in alphabetical order by action. They’re listed in the format Action - Shortcut, where Action is what will happen when you press the key combination in Shortcut. If you want to use a built-in key set, then select a mapping that matches your operating system. Pay close attention to the different keys and make sure your keyboard has them!

Creating Your Own Shortcuts

The customization of the keyboard shortcuts is very similar to the customization of syntax highlighting colors. Unfortunately, IDLE does not allow you to install custom keyboard shortcuts from a file. You must create a custom set of shortcuts from the Keys tab.

Select one pair from the list and press Get New Keys for Selection. A new window will pop up:

Here, you can use the checkboxes and scrolling menu to select the combination of keys that you want to use for this shortcut. You can select Advanced Key Binding Entry >> to manually type in a command. Note that this cannot pick up the keys you press. You have to literally type in the command as you see it displayed to you in the list of shortcuts.


The fourth tab of the customization window is a place for small, general changes. The general settings tab looks like this:

Here, you can customize things like the window size and whether the shell or the file editor opens first when you start Python IDLE. Most of the things in this window are not that exciting to change, so you probably won’t need to fiddle with them much.


The fifth tab of the customization window lets you add extensions to Python IDLE. Extensions allow you to add new, awesome features to the editor and the interpreter window. You can download them from the internet and install them to right into Python IDLE.

To view what extensions are installed, select Options → Configure IDLE -> Extensions. There are many extensions available on the internet for you to read more about. Find the ones you like and add them to Python IDLE!


In this tutorial, you’ve learned all the basics of using IDLE to write Python programs. You know what Python IDLE is and how you can use it to interact with Python directly. You’ve also learned how to work with Python files and customize Python IDLE to your liking.

You’ve learned how to:

  • Work with the Python IDLE shell
  • Use Python IDLE as a file editor
  • Improve your workflow with features to help you code faster
  • Debug your code and view errors and exceptions
  • Customize Python IDLE to your liking

Now you’re armed with a new tool that will let you productively write Pythonic code and save you countless hours down the road. Happy programming!
