__init__ return value

[Batista, Facundo]

Studying the Tim Peter's FixedPoint code, found this:

# can we coerce to a float?
yes = 1
try:
asfloat = float(value)
except:
yes = 0
if yes:
self.__init__(asfloat, p)
return

This code is part of the __init__ method of the class.

The question is about the last two lines: When you call self.__init__(...),
doesn't it return a value that you should return too?

I thought it could be like this:

....
if yes:
newobject = self.__init__(asfloat, p)
return newobject

Thanks for all.

No. __init__(self) returns None. In fact, I'm not certain whether
it even checks for the value of the return. __init__()'s function is
to initialize the instance which is it's first parameter, you cannot
change the instance it is working on.

If you need to provide your own instance object, use __new__().
