How to make a 3 column quickref cheat sheet?

I’ve been trying to use MS Word (Office 365) to make a 3 column landscape quickref of Python commands as I learn them, but Word is terrible. It seems buggy and it won’t reformat things the way I like. And I don’t want to give my email to someone to get their quickref sheet and get spammed.

What do you use to make a cheat sheet?

Thank you.
