I get asked all of the time how to install Python on Windows and Mac so I decided to make a tutorial that shows how to do it. I also show how to set up the Atom text editor so that the code will run in a console inside of it because that is another common request.

This is also going to be needed because I want to answer the most common question I get which is how to start programming. That tutorial will start soon while I continue all the others I’ve already started. Step-by-step directions follow the video below.
