Installing Python

Installing Python means setting up the Python software on your computer so you can start writing and running programs. It is the first step in learning Python programming.

Installing Python is like installing a game before playing it you must set it up before using it.

Once installed, your computer can understand Python code and execute programs.

This is the first step in learning python programming. 

There are two ways to write and execute python programs. 

1. Using the online editors (online platforms).
    -directly with the help of internet, you can write and execute your python 
     programs.
 
     main.py
     main --> name of your program 
     .py  --> extension of your file name (it is a python program)

     if there is no internet connection, you cannot execute your programs. 

2. Using the installation of python software in your computer. 
    once you installed, even if you don't have internet connection you can still write and execute your python programs.
