And before Python 2.2 there was the UserList class in the standard

Apart from compatibility issues as mentioned in the UserList
documentation, deriving from it will give you a classic class,
whereas deriving from list will give you a new style class.
There may be circumstances under which this is important
(exercise left to more twisted minds than mine). Same applies
to dict/UserDict.
Classic classes will eventually disappear:

GvR also encourages people to use new-style classes for everything:
