In this video, I show how to install Python on computer running Windows. There is one step that its very easy to skip. When you first run the installer, you need to check a box that says:
Add Python 3.7 to PATH
If you skip that step, you’ll have no way to install libraries, like cs50 and pygame, on your machine. I call it out in the video as well, but I’m writing it here because its so easy to miss.
