How do I run pip on python for windows?

Maybe you’d like try run pip in Python shell like this:

>>> import pip
>>> pip.main(['install', 'requests'])

This will install requests package using pip.

Because pip is a module in standard library, but it isn’t a built-in function(or module), so you need import it.

Other way, you should run pip in system shell(cmd. If pip is in path).
