To me it seems you should do it something like this: -def f(x): - class C(object): - def __init__(self, x): - self.x = x # here you set the attribute for class C - c = C(x) # instantiate a C object - print c.x
-f(5)
That does something different - in this case, x is an instance variable, not a class variable.
You do raise an interesting questions though:
Py> def f(x): ... class C(object): ... x = None ... def __init__(self): ... if C.x is None: ... C.x = x ... C() ... print C.x ... Py> x = 5 Py> f(6) 6
So, the real problem here is the interaction between the ability to write "<name> = <name>" in a class definition with the reference on the RHS being resolved in the global namespace and nested scopes (since that first lookup does NOT respect nested scopes).
Functions don't have the problem, since they don't allow that initial lookup to be made from the outer scope.
Cheers, Nick.
