Here is a useful (moderately advanced) technique:

def factory(arg):
    def foo(x=arg):
        print "My name is", foo.__name__
        print "My result is", x + 1
    return foo

class spam:
    pass

for i in range(10):
    name = "method_%d" % i
    f = factory(i)
    f.__name__ = name
    setattr(spam, name, staticmethod(f))


But:

>>> spam.method_0(1)
My name is method_0
My result is 2
>>> spam.method_7(9.4)
My name is method_7
My result is 10.4
