Also, do y'all call main() in the if block or do you just put the code you want to run in the if block?

Yes, because

In the first kind of language, the thought process is basically: I have the flow of execution, starting at the top of the file. If I want to make a library, I should build the things I want to build, then get out of the way.

Note the "I have the flow of execution", and the "if I want to build a library".

If you just want to build an executable, do as you wish, you already have the flow of execution.

If you want to build a library, make the relevant classes and functions and get out of the way (i.e., no IO, no long-running tasks).

If you want to combine them, use the main name check - or, make a package and do entry points that way. Either way works, because both can fulfill the goal of staying out of the way of those importing this as a library.
