11. Class Decorators

Class decorators allow you to modify or enhance classes in a reusable way.

Example​

def add_repr(cls):
    cls.__repr__ = lambda self: f"<{cls.__name__} {self.__dict__}>"
    return cls

@add_repr
class Person:
    def __init__(self, name):
        self.name = name

p = Person("Alice")
print(p)

Wrap-Up​

Class decorators are similar to function decorators but operate on classes instead of functions.
