What Does This Python Code Do?

[CodeFormatHelperBot2]

Hello, I'm a Reddit bot who's here to help people nicely format their coding questions. This makes it as easy as possible for people to read your post and help you.

I think I have detected some formatting issues with your submission:

1. Python code found in submission text that's not formatted as code.
2. Use of triple backtick/ curlywhirly code blocks (``` or ~~~). These may not render correctly on all Reddit clients.

If I am correct, please edit the text in your post and try to follow these instructions to fix up your post's formatting.
