Examples
>>> @dataclasses.dataclass() ... class Item: ... name: str ... unit_price: float = 1.00 ... quantity_on_hand: int = 0 ...
>>> @dataclasses.dataclass(repr=False) ... class ItemWithMixin(SkipDefaultFieldsReprMixin): ... name: str ... unit_price: float = 1.00 ... quantity_on_hand: int = 0 ...
>>> Item('Test') Item(name='Test', unit_price=1.0, quantity_on_hand=0)
>>> ItemWithMixin('Test') ItemWithMixin(name=Test)
>>> Item('Test', quantity_on_hand=2) Item(name='Test', unit_price=1.0, quantity_on_hand=2)
>>> ItemWithMixin('Test', quantity_on_hand=2) ItemWithMixin(name=Test, quantity_on_hand=2)
If you want to copy/paste the
__repr__()
directly, you can omit therepr=False
:>>> @dataclasses.dataclass ... class ItemWithMixin(SkipDefaultFieldsReprMixin): ... name: str ... unit_price: float = 1.00 ... quantity_on_hand: int = 0 ... __repr__ = SkipDefaultFieldsReprMixin.__repr__ ...
>>> ItemWithMixin('Test') ItemWithMixin(name=Test)
>>> ItemWithMixin('Test', unit_price=2.00) ItemWithMixin(name=Test, unit_price=2.0)
>>> item = ItemWithMixin('Test') >>> item.unit_price = 2.05
>>> item ItemWithMixin(name=Test, unit_price=2.05)
