Although knowledge of Python internals is not strictly required for Python programming, a basic understanding of the runtime structure of Python can help you grasp the bigger picture of program execution.
When you instruct Python to run your script, there are a few steps that Python carries out before your code actually starts crunching away. Specifically, it’s first compiled to something called “byte code” and then routed to something called a “virtual machine.” Lets understand these in detail.
Internally, when you execute a program Python first compiles your source code (the statements in your file) into a format known as byte code. Compilation is simply a translation step, and byte code is a lower-level, platform-independent representation of your source code. Roughly, Python translates each of your source statements into a group of byte code instructions by decomposing them into individual steps. This byte code translation is performed to speed execution — byte code can be run much more quickly than the original source code statements in your text file.
If the Python process has write access on your machine, it will store the byte code of your programs in files that end with a .pyc extension (“.pyc” means compiled “.py” source). Prior to Python 3.2, you will see these files show up on your computer after you’ve run a few programs alongside the corresponding source code files — that is, in the same directories. For instance, you’ll notice a script.pyc after importing a script.py.

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:

You should probably know how to run Python scripts if you are familiar with Python.
Why should you read this article? And another chance that you don’t know how to run Python scripts as you are not familiar with them. It’s definitely for you. Is this only for you? No, both who are familiar and who are not with Python can get something new in this article. Without further ado let’s jump into the article.
Before going into the execution part of the tutorial, we need to have installed Python on our systems.
Open a text editor and create a Python script to use throughout this tutorial. You can use the following script of adding two numbers.
a, b = list(map(int, input().split())) print(a + b)

If you are using Linux, then you would definitely love the shell commands.
And if you are working with Python, then you may have tried to automate things. That’s a way to save time. You may also have some bash scripts to automate things.
Python is handy to write scripts than bash. And managing Python scripts are easy compared to bash scripts. You will find it difficult to maintain the bash scripts once it’s growing.
But what if you already have bash scripts that you want to run using Python?
Is there any way to execute the bash commands and scripts in Python?
Yeah, Python has a built-in module called subprocess which is used to execute the commands and scripts inside Python scripts. Let’s see how to execute bash commands and scripts in Python scripts in detail.

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.
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')
