I don't understand why this code
Code:
class player:

    name = ''
    hand = []

    def __init__(self, name=""):
        self.name = name

class test:
    def addItem(self, recipient, item):
        recipient.hand.append(item)

def main():
    me = player("LaundroMat")
    him = player("Someone else")

    t = test()
    t.addItem(me, "Apple")

    print him.hand
      

if __name__ == "__main__":
    main()

results in
Code:
['Apple']

It appears by calling another classes method, the list is shared?
 
I'm just learning python myself, but I think your problem is that the attribute is not created as part of the __init__. This appears to work the way you want:
Code:
class player:

    name = ''


    def __init__(self, name=""):
        [red]self.name = name[/red]
        self.hand = []

class test:
    def addItem(self, recipient, item):
        recipient.hand.append(item)

def main():
    me = player("LaundroMat")
    him = player("Someone else")

    t = test()
    t.addItem(me, "Apple")

    print him.hand
      

if __name__ == "__main__":
    main()[/code

Sorry for the late reply, but thanks! It works.

Maybe the Python docs should be a bit more explicit about this.
