if you're going to post questions to arbitrarily chosen threads, youcould at least change the subject (but it's a lot nicer to open a newthread).the "**" prefix tells Python to stuff any excess keyword arguments into
the given variable: >>> def func(**kwargs):... print kwargs... >>> func(){} >>> func(spam=1, egg=2){'egg': 2, 'spam': 1}for more on Python's parameter syntax, see the section on "def" in the
language reference; see e.g. http://effbot.org/pyref/def.htm--http://mail.python.org/mailman/listinfo/python-list

class Base2(Base1): passclass Base3:    def amethod(self):    print "Base3"class Derived(Base2, Base3): passaninstance = Derived()aninstance.amethod()
