I figured it out with google's help. Here's my demo code:
def __init__(self, parentmethod):
self.parentmethod = parentmethod
def more(self, value):
self.label = 'blarg'
self.stuffs = child(self.set_label)
self.label += "1"
In the demo you instantiate parent and then just use the more method
to append values to the child list, and when its used it also calls
the parent method set_label. :)
Thanks for all your help, I really appreciate it!
