Hi,
I am trying to write a python class with a new data type such as:
class Cc14:
def __init__(self, realpart, imagpart):
self.r=realart
self.i=imagpart
def __saturator(x):
return x+1
def out(self,x):
return Cc14(__saturator(x.r), __saturator(x,i))
When I use the method out such as:
z.out
Python complains:
global name '_Cc14_saturator' is not defined.
Is the way put two underscore in front of the definitio making the method
becomes private?
Why in the same clase, I could not use the __saturator method?
Thanks
Frank
