I learned Python about 5 years ago, just for context, I know a bit of bash, some html/css etc. I don't really understand this piece. I use Classes in Python, put them in a module, I also put functions there. Some things are nice as a class, some things are nice as general functions. I like inheritance, otherwise I repeat things. Maybe I need to grow my project and run into limitation before I understand the viewpoints. Maybe anyone has to go through this? Should I feel bad about using classes/objects?
