The OP's probably is that during the execution of the class body, the

the function itself, and its globals don't either. You just can't do
that.
The right way, IMHO, is to move 'fact' up and out of the class into a
_fact global variable. Alternatively, you can use a metaclass.
Note that you can also pass a function to the function itself, and then
it works:
class Foo:
... def func(foo=None):
... if foo:
... return foo()
... else:
... return '2nd step'
... x = func(func)
...
Foo.x
'2nd step'
Note that when called from class definition body, func is an ordinary
function, not a method. It become a method *when it's called as a method*
(what is possible *after* creating the class => outside the definition).
