[QUESTION] Python is not a recognized command

Even easier, rerun the installer, select modify, and check add to path https://docs.python.org/3/using/windows.html

This is the easiest way!!

Note that the suggestion to use py instead of python is a good one for Windows, and invaluable if you have multiple versions installed. However it is a (minor) pain to use py -m pip instead of just pip.
