Well, I thought to throw this out for fun:

>>> listSet = set(dir(list))
>>> tupleSet = set(dir(tuple))

>>> listSet - tupleSet
{'sort', 'insert', '__reversed__', 'reverse', 'extend', '__delitem__',
 '__setitem__', '__iadd__', 'pop', 'append', '__imul__'}

>>> tupleSet - listSet

That would explain the major differences... =]
