What are some common mistakes people make when using classes in Python?

Some common mistakes include not using the self parameter, forgetting to initialize attributes, and misusing inheritance.

Can you explain why forgetting to use self is a problem?

Forgetting self means that the method won't have access to instance variables, leading to errors or unexpected behavior.

What about initializing attributes? Why is that important?

If attributes aren't initialized in the __init__ method, they won't exist when you try to access them, causing an AttributeError.

How can I avoid these mistakes in my code?

You can avoid these mistakes by following best practices, using linters, and writing unit tests to catch errors early.
