What you said, and that his solution sounds like a Java approach to the
problem (subclass an abstract base class that calls specific methods on
the subclass to "do the right thing").
To offer the OP source he can use...
class Map:
def __init__(self):
self.dict = {}
def DoSomething(self):
#do something with self.dict
Every instance gets a new dictionary. Now, if he actually wants to
change the behavior of the DoSomething method, of course then it would
make sense to subclass Map.
