How do getattr and setattr work in Python?

Can you explain how getattr and setattr work in Python?

Sure! getattr is used to access an attribute of an object dynamically, while setattr is used to set an attribute's value.

Can you give me an example of how to use them?

Of course! If you have an object obj and you want to get the value of its attribute name, you can use getattr(obj, 'name'). To set it, you would use setattr(obj, 'name', 'New Name').

What happens if the attribute doesn't exist?

If the attribute doesn't exist and you use getattr, it will raise an AttributeError unless you provide a default value. For example, getattr(obj, 'nonexistent', 'default') will return 'default' instead.

Can I use these functions with built-in types?

Yes, you can use getattr and setattr with built-in types like lists and dictionaries, but be cautious as it may lead to unexpected behavior.
