Introduction to Python:

Introduction:

Python is an extremely popular computer programming language. Its popularity lies in the fact that its procedural but at the same time object oriented too. Its interpreted but compiled too. Its high level but provides many low-level interfaces for the operating system too.

In short, Python is an interpreted, high level, object-oriented programing language. It was developed by Guido Van Rossum in 1991. However unlike of many other languages, python has gone through continuous upgrades and feature enhancements. The first major release was 3.0 in 2008. After that all the versions are canonically written as 3.x

   3. The checkbox Install launcher for all users will install python in a way that it is available for all the user accounts on that PC.
   
   
   4. The checkbox Add Python to PATH lets the Python installer add an environment variable as well. As long as we have to work on the default libraries and functions, adding PATH is not needed at all but if we need to install some external libraries, it is required.


5. Once the installation is successfully completed, we are ready to work on Python.
