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
Here's one for for office workers using a computer shared by others.
I did put my user path in path and created the PYTHONPATH variables in my computer's PATH variable. Its listed under Environment Variables in Computer Properties -> Advanced Settings in Windows 7.
Example:
C:\Users\randuser\AppData\Local\Programs\Python\Python37
This made it so I could use the command prompt.
Hope this helped.
