Sure, but a lot of people incorrectly think the __eq__ and __hash__ are defined based on value not identity, as they are for many other types say float, str, or tuple. But for a class the default __eq__ method is x is y instead of x == y and also __hash__ is based on identity.

Others assume that if you don't define __hash__ for a class, that it doesn't exists (like for list, set, or dict) so that a "TypeError: unhashable type: 'Value'" exception is raised.

I thought it was an interesting exercise to share, but maybe too simple for this audience, or people are just not aware of the basic steps that happen when adding and searching values in a set/dict. Try the same with type int:

v1 = 1001
v2 = 1002
myset = {v1}
print(v1 in myset, end=' ')
v2 = 1001
print(v2 in myset, end=' ')
v1 = 1002
print(v1 in myset, end=' ')

and you see a different output. To do the same with the Value class add methods:

def __eq__(self, other):
    return self.value == other.value

def __hash__(self):
    return hash(self.value)
