An "argument" is something that is specified in the the function
call. I assume you are trying to state something like, "fact() is not
defined with a parameter variable named self". However, that has
never been a requirement in python:
class A(object):
def fact(n):
print n
fact("hello")
a = A()
a.fact()
--output:--
hello
<__main__.A object at 0x7faf0>
