"'str' object has not attribute 'intersection'": apparently, something is really a string (an 'str') while you expect it to be a set. "unhashable set": maybe, you try to put a set into another set (or a dict; or somewhere else where hashability is necessary). A "set" itself is unhashable (like many mutable standard data types); you may consider to use "frozenset" in those cases (of course, a "frozenset" is immutable, i.e. cannot be changed after creation). -- https://mail.python.org/mailman/listinfo/python-list
