Yes, by using instance-attributes instead of class-attributes, as you do.

Btw, it's common to name classes in python with a capital first letter, and
you should use new-style classes, which means you need to subclass it from
object:

class Document(object):

    def __init__(self):
        self.haveWords = set()
