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
