Can I choose which version of python I work on in the CMD when I start working?

Question

I have 3 versions of python in my computer. They are 2.7, 3.5 and 3.6. But my default python that opens in cmd is 3.5.

Answer 1

either you change the path you set up in the environment variables or open the command prompt from the root folder of the version of Python you want to use.
