What is dataclass?
Dataclass (also called @dataclass): A class decorated with @dataclass that automatically generates __init__, __repr__ and __eq__ from annotated fields. It removes boilerplate for classes that mainly hold data, such as configuration records. It is part of the standard library from Python 3.7 onward.
Dataclass: an example
@dataclass class Config: lr: float = 0.001; epochs: int = 10 then Config(epochs=5) works with no hand-written __init__.
