Python not working in command prompt?

Question

I type python into the command line, but the command prompt says that python is not recognized as an internal or external command, operable program, or batch fi

Answer 1

Even after following the instructions from the valuable answers above, calling python from the command line would open the Microsoft Store and redirect me to a page to download the software.

I discovered this was caused by a 0 Ko python.exe file in AppData\Local\Microsoft\WindowsApps which was taking precedence over my python executable in my PATH.

Removing this folder from my PATH solved it.
