... dictionaries [...]". The 'invalid dict' above with list keys is not valid python code - dict keys must be immutable. Therefore you are not comparing dictionaries. If you try and use a list as a dictionary key your code will not run. You have no objects for which to compare. This is like typing x = ...
Best way to find the intersection of multiple sets?
...
From Python version 2.6 on you can use multiple arguments to set.intersection(), like
u = set.intersection(s1, s2, s3)
If the sets are in a list, this translates to:

class Property:
"Emulate PyProperty_Type() in Objects/descrobject.c"

...set_name(self, new_name):

self.name = A
running function set_name()
self.name = B
>>> a.name
'B'
The example above is silly, but it works.
