I haven't done much Python in the past, so I was wondering if you could look over my code and make sure everything is up to snuff?
I know programs that do this exist already, but I am having a challenge with my friend on who can build a simple backup system for our college files.
I have run the code through Pylint and a PEP8 code checker, and fixed the errors it produced.
