New submission from Colin <[email protected]>:
Hi,
When using inheritance with dataclass, "standard" instance methods that are
provided with a default behavior thanks to dataclass are not overridable using
inheritance.
Please see the sample below (or the attached file):
import dataclasses
@dataclasses.dataclass
class A:
def __eq__(self, other):
return True
@dataclasses.dataclass
class B(A):
pass
print(A() == 1) # Returns True as expected
print(B() == 1) # Returns False instead of True as expected via inheritance
Thanks again
