23.2    Class Decorators

The principle of function decorators can be applied in a similar way as class decorators, with the only difference being that the object to be manipulated is not a function but a class.

From Chapter 19, Section 19.12, you already know about the data classes that are defined using a class decorator:

>>> import dataclasses>>> @dataclasses.dataclass... class SomeDataClass:...     python: str...     works: int...     well: list>>> SomeDataClass("Test", 123, ["A", "B", "C"])SomeDataClass(python='Test', works=123, well=['A', 'B', 'C'])  

Much like the previous examples on function decorators, this definition of a data class can also be formulated as follows:

>>> class AnotherDataClass:...     python: str...     works: int...     well: list>>> AnotherDataClass ...
