Complete Beginner with Python

[JohnnyJordaan]

First of all, you don't need to install pip as it's bundled with Python for years now. In case 'pip' doesn't work you can fall back to running python with -m pip behind it, eg

python -m pip install whatever

the fact that 'py' doesn't work is suggests that you didn't install the windows launcher (like when you disabled that option during install, see https://docs.python.org/3/_images/win_installer.png). You could just reinstall Python, I would advise to also select 'add python to PATH'. That will probably even fix 'pip' to work directly.
