7.5 Using dataclasses for mutable objects
We’ve noted two general kinds of objects in Python:
Immutable: During design, we’ll ask if something has attributes with values that never change. If the answer is yes, see the Using typing.NamedTuple for immutable objects recipe, which offers a way to build class definitions for immutable objects.
Mutable: Will there be state changes for one or more attributes? In this case, we can either build a class from the ground up, or we can leverage the @dataclass decorator to create a class definition from a few attributes and type hints. This case is the focus of this recipe.
How can we leverage the dataclasses library to help design mutable objects?
7.5.1 Getting ready
We’ll look closely at a mutable object with an internal state to represent a hand of cards. While individual cards are immutable, they can be inserted into a hand and removed from a hand...
