Here's an example:
class Test(object):
def __init__(self):
self.lst=[1,2,3]
self.map={"foo":12,"bar":34}
This is a container that has a list and a dictionary in it. When an
instance of the container is destroyed, its list and dictionary will
be destroyed too (assuming nobody's made other references to them).
You don't need to code anything explicitly for that.
