Hi,
i have some questions related to new style classes, they look
quite useful but i wonder if somebody can give me an example
on constructors using __new__ and on using __init__ ?
I just see that when using it i can't give parameters to __new__
and when i additionally define __init__ then __new__ is not
called.
So i can use __new__ only for classes whose constructors don't
have parameters?
class C2:
def __new__(self):
print "new called"
self.a = 8
def __init__(self, a):
print "init called"
self.a = a
def fct(self):
print self.a
a = C2(7)
a.fct()
This way __new__ is not called, if i remove __init__ then
there are too many parameters to __new__, if i add a parameter
to __new__ then it says that __new__ does not take arguments.
Thanks for any hints,
Torsten.
