Hi,I'd like to have a reference to an instance attribute as default argument in a method. It doesn't work because "self" is not defined at the time the method signature is evaluated. For example: class C(object): def __init__(self): self.foo = 5 def m(self, val=self.foo): return val Raises NameError because 'self' is not defined. The obvious solution is put val=None in the signature and set val to the appropriate value inside the method (if val is None: ...), but I wonder if there's another way. Cheers, Ernest
your 'val=None' is jus fine. JM -- http://mail.python.org/mailman/listinfo/python-list
