Run different Python versions from cmd in windows

Hello guys,

If someone has 2 different python versions installed in their pc

eg: Python 2 and Python 3

Which python do you want as your primary python, set that to first in environment variables in windows

1)go to start -- environment variables
2)a dialog will open up and in the bottom right corner you'll find environment variables
3)click that
4)User variables for ADMIN and System Variables
5)variable -- Path (you'll find in both)
6)if you want you can set in both or just in User variables for ADMIN
7)ok

Open a fresh terminal/cmd

below are the command lines to open different versions

py -3

py -2

That is it guys for today.
