Contortion ? Which contortion ?

class Foo(object):
    def __init__(self, name):
        self.name = name

def greet1(self, who):
    print "hello %s, this is %s" % (who, self.name)

def greet2(self, who):
    print "Yo %s, have a drink with Daddy %s" % (who, self.name)

f = Foo('Python')

Foo.greet = greet1
f.greet('Monty')
Foo.greet = greet2
f.greet('Monty')
