Demystifying decorators: They don't need to be cryptic (thepythoncodingstack.com)
I avoided decorators for so long. First, I pretended they didn't exist. Then, I treated them like a magic spell—I'd use some of the common ones and simply copy how they're used in the documentation. And each time I tried to learn how they work, I'd give up pretty quickly.

Using Python's .__dict__ to Work with Attributes – Real Python (realpython.com)
Python’s .__dict__ is a special attribute in classes and instances that acts as a namespace, mapping attribute names to their corresponding values. You can use .__dict__ to inspect, modify, add, or delete attributes dynamically, which makes it a versatile tool for metaprogramming and debugging.
