Need help installing and running Pygame.

I am starting a Skillshare course that revolves around Pygame and building games. Whenever I run my code, after importing Pygame, I always get the error "No module named 'pygame'". I've read what seems like hundreds of forums to try and fix this issue. I know I'm running the 64 bit python version and have successfully installed the latest version of Pygame from GitHub on Mac and have used the terminal command "pip3 install Pygame". Still, whenever I test if Pygame is installed in idle with "import Pygame" I get an error message that says "no module named Pygame". Please help

tldr: Running python 64-bit on newest Mac software and can't get Pygame to work regardless of the strategy used.
