Title
Body
When implementing a class with multiple properties (like in the toy example below), what is the best way to handle hashing? I guess that the __eq__ and __hash__ should be consistent, but how to implement a proper hash function that is capable of handling all the properties? class AClass: def __init__(self): self.a = None self.b = None def __eq__(self, other): return other and self.a == other.a and self.b == other.b def __ne__(self, other): return not self.__eq__(other) def __hash__(self): return hash((self.a, self.b)) I read on this question that tuples are hashable, so I was wondering if something like the example above was sensible. Is it?
