Python Forum

Hello,
I'm just beginning to teach myself python. This is one of my toy programs for learning and I would really appreciate feedback to gauge things like style, efficiency, logic, etc...

Also, I was wondering if there is a way to use a list comprehension for the statements in the functions (make_close_under & make_veryclose_under).

Thank you in advance for your time and help!

@RickyWilson - That's helpful, thank you very much.
