Basically 'args' is a tuple with all the positional arguments, kwargs is a dictionary with all the named arguments. Likewise you can pass a tuple to a function like func(*tuple), or a dict like func(**dictionary) or both, where the zuple has to come first. -- http://mail.python.org/mailman/listinfo/python-list
