e = ExampleList([1,2,3,4], 2) >>> e.firstpart [1,2] rather than >>> e.firstpart() [1,2] We can implement this using properties, and I will refer you to some of the documentation http://docs.python.org/library/functions.html#property Here is just one way that you could simply implement a property in your case: class ExampleList(object): """Note that this is a new style class.""" def __init__(self, sequence, position): self._sequence = sequence self._position = position @property def firstpart(self): """This method will be called on inst.firstpart rather than inst.firstpart().""" return self._sequence[:self._position] Here I have used property as a decorator (described in the link), now you can get your firstpart through attribute access (not that you cannot 'set' to it): e.firstpart Cheers,
