New submission from Madhav Datt:
The problem is described with an example in this StackOverflow question
(https://stackoverflow.com/questions/26589805/python-enums-across-modules).
Like in C and other languages, I would expect Enum equality to work across
modules and not compare enum states/values, instead of just checking for the
same object.
A possible simple fix for this problem would be to override the __eq__()
function by default in the enum.Enum class with the following:
def __eq__(self, other):
if isinstance(other, self.__class__):
return self.value == other.value
return False
I would be happy to create a GitHub pull request to fix this, however, I do not
have the experience or knowledge to know if
- the current behavior is by design;
- whether this is worth fixing; and
- whether fixing this will break anything else.
