You have to do the method dispatching by yourself. For variable
length parameter list you could choose this solution:
def __init__(self, *args):
if len(args) == 1: self.__setup1(*args)
elif len(args) == 2: self.__setup2(*args)
...
def __setup1(self, arg1):
print "setup1"
def __setup2(self, arg1, arg2):
print "setup2"
Or for different parameter lists which may have the same length my
suggestion would be:
def __init__(self, **kw):
self.__dict__.update(kw)

PS: anyone working on a patch for multimethod dispatching for python?
