Python programming is free and easy to learn. Before you start doing Python programming, you need to install a Python interpreter. The latest version of python is python 3.8.1(3.X), Which you need to download from python.org and install it.

Most of the python tutorials assume that the user knows how to write and run the program. Once you downloaded the python installation file, follow the below steps. Whether you are a Windows user or a Mac user, you can follow the same steps.
