How to Format Integers into String Representations in Python

By reading this piece, you will learn to format an integer (123456) into its own string representation (123K) in Python. This helps to improve the user experience in your application as displaying the number as string representation is a lot more coherent to the users. In this tutorial, I am going to showcase two different implementations:

• a modified version of the codes shared on Stack Overflow
• my own custom implementation

Having said that, this article does not cover string representation that is less than 0 such as micro and nano. Feel free to implement it on your own once you have completed the tutorial.

Lambda, Map, Filter functions in python

Welcome to my Blog, In this article, we will learn python lambda function, Map function, and filter function.

Lambda function in python: Lambda is a one line anonymous function and lambda takes any number of arguments but can only have one expression and python lambda syntax is

Syntax: x = lambda arguments : expression

Now i will show you some python lambda function examples:

String Format() Function in Python

To control and handle complex string formatting more efficiently

What is formatting, why is it used?

In python, there are several ways to present output. String formatting using python is one such method where it allows the user to control and handle complex string formatting more efficiently than simply printing space-separated values.There are many types of string formatting, such as padding and alignment, using dictionaries, etc. The usage of formatting techniques is not only subjected to strings. It also formats dates, numbers, signed digits, etc.

Structure of format() method

Let us look at the basic structure of how to write in string format method.

Syntax: ‘String {} value’.format(value)

Let us look at an example:
‘Welcome to the {} world.’.format(“python”)

Here, we have defined a string( ‘’) with a placeholder( {} ) and assigned the argument of the parameter as “python.” On executing the program, the value will be assigned to the placeholder, showing the output as:

#python #programming #string format() function in python #string format() function #format() #format() function

TypeError: String indices Must Be Integers - Python

Python throws typeerror string indices must be integers when you try to index strings using another string. For example –

>>> superhero = 'Captain America'
>>> print(superhero[1])
a
>>> print(superhero["2"])
Error: string indices must be integers

PythonCopy

In this code, we are defining a string variable superhero which is indexed as superhero[1] and superhero["2"]. superhero[1] is correct but superhero["2"] will raise “string indices must be integers” error.

We use string indices in case of dictionaries and json data. If you have defined a dictionary or json and still getting this error, then it means due to some part in the code you are either reassigning the variable as string or some library doing that.

Python Tricks Every Developer Should Know

Python is awesome, it’s one of the easiest languages with simple and intuitive syntax but wait, have you ever thought that there might ways to write your python code simpler?

In this tutorial, you’re going to learn a variety of Python tricks that you can use to write your Python code in a more readable and efficient way like a pro.

Let’s get started

Swapping value in Python

Instead of creating a temporary variable to hold the value of the one while swapping, you can do this instead

>>> FirstName = "kalebu"
>>> LastName = "Jordan"
>>> FirstName, LastName = LastName, FirstName 
>>> print(FirstName, LastName)
('Jordan', 'kalebu')
