How do I add Python to the Windows PATH?

I want to be able to run Python commands from the Windows CMD. However, if I don't specify Python's full path for each command, I get an error saying "Python is not recognized as an internal or external command, operable program or batch file."

How do I add Python to the Windows PATH permanently?
