A newbie question

[wang frank]

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 __add__(self,x):
return self.r+x,r, self.i+x.i

If I have
x=Cc14(4,5)
y=Cc14(4,5)
z=x+y

z will be a tuple instead of Cc14. How can I return a Cc14 class?

Thanks
Frank

How about this:

    def __add__(self,x):
        return Cc14(self.r+x.r, self.i+x.i)

However... Are you aware that Python has built in support for complex
numbers already?

return Cc14(self.r+x,r, self.i+x.i)

FYI, Python has a built-in "complex" type.
