What's wrong here?
I have the next idea for this task. There's self._friends = dict of: key - one friend value - set of his friends
I have the next remove method def remove(self, connection): it = iter(connection) friend1, friend2 = next(it), next(it)
ret = False if friend1 in self._friends and friend2 in self._friends[friend1] or\ friend2 in self._friends and friend1 in self._friends[friend2]: ret = True if ret: self._friends[friend1].remove(friend2) self._friends[friend2].remove(friend1) if not self._friends[friend1]: del self._friends[friend1] if not self._friends[friend2]: del self._friends[friend2] return ret
But test3/3 fails by return boolean value. Dunno what to do. Just tell me if that mistake by me? or not?
