1. starting Python from Idie

Idle is a python shell,shell meaning "shell", which is basically a way of interacting with the program by entering it. Windows like the cmd window, like the Black Command window of Linux, are all shells and can be used to give commands to the operating system. Similarly, you can use the idle shell to interact with the Pytho.

2. Try something new

Try something new, enter print (5+3) in idle, or enter 5+3 directly

>>> print (5+3) 8>>> 5+38

It looks like Python will do the addition! That's not surprising, because computers are used to calculate when they start, and any programming language has computing power, so let's look at Python's calculations.
