Your code is inverted from Raymond's:

One side note: The obvious trivial solution:
def findset(s, e):
for i in s:
if e == i:
return i
return None
is because of its complexity

Hi group,
I have a very simple about sets. This is a minimal example:
#!/usr/bin/python
class x():
def __init__(self, y):
self.__y = y
def __eq__(self, other):
return self.__y == other.__y
def __hash__(self):
return hash(self
