Python Hash list check

[here2learn]

Hi All, 

First post!

I'm Looking for a bit of help with a small task. 


I am pretty new to python and have a program which generates a list of hashes in either md5 or sha256 (users choice) for every file in a directory and subdirectories using oswalk then outputs that list to a report, example below.

('Format = hash,filename ', '/users')
284d3b132b8586183474ff8c5e396d3a62b9b9fd7cafb448e137d0ec493ad5ce         /users/"username"/.bash_history

I'm look for help on how to compare the hashes in the report file with a list list of known good ones. I'm completely stuck on how to get this started.

Any help would be greatly appreciated.
