Introduction
In the last article "
Learning Python - Introduction To Python", we discussed what Python is and most importantly, why to learn Python. In this article, we will discuss the steps to install Python on a Windows machine. I have Windows 10 on my laptop.
The following are the detailed steps to install Python on Windows 10.
- Download the latest version of Python for Windows 10 - Download Python for Windows from here. The download page can be visited from here as shown below.

- Finally, there is the quit() command available to exit the shell

Note
Here, these commands are case sensitive. This means if we will use “Keywords” instead of “keywords” we will get an error as,
Fig 13: Python: error for “Keywords" - its case sensitive, it should be “keywords”
Summary
Also, regarding Python Keywords, Topics, Modules, Symbol, we will discuss in detail in upcoming articles.
