I would add... modern Python on Windows includes pip, but pip is not in
the same directory as Python. So if you told the installer to add Python
to the path you could have something like (this is an example):

C:\Users\Foo\AppData\Local\Programs\Python\Python36-32

in your PATH, but pip is in the path

C:\Users\Foo\AppData\Local\Programs\Python\Python36-32\Tools

you can add the latter to your PATH as well; or, use

  python -m pip dosomething

in place of

  pip dosomething

That is, even if Windows doesn't have pip in its path, Python shguld
know how to find it as a module.
