Understanding Python Instance __dict__

Learn how Python's instance __dict__ stores attributes, how to inspect and modify it, and when __slots__ offers a better memory tradeoff.

Python Unbound Method: What It Is and How It Changed

An unbound method in Python 2 is the object you get when you access an instance method through the class. Python 3 replaces it with a plain function. See what changed and how to handle the difference.
