Re: 'new' module deprecation in python2.6
Hi Mike. Many thanks for your reply and thank you for reference. I
have code that looks like the following so initially looking at what
will need to be done as it doesn't appear new will survive. So first
need to find way of translating this sort of thing using types. I see
there is a ClassType for types in Python 2.6 but it does not exist in
Python 3 so wonder where this is going? Is this an oversight or maybe
just not ready yet.
import new
class FirstBase(object):
foo = 'bar'
biz = 'baz'
class SecondBase(object):
bla = 'blu'
buz = 'brr'
attr = {
'fiz': 'An attribute', 'fuz': 'Another one'}
Test = new.classobj(
'Test', (FirstBase, SecondBase), attr)
class MyNewClass(Test):
pass
a = MyNewClass()
print a.foo, a.buz, a.fiz, type(a)

Re: 'new' module deprecation in python2.6
Yeah, can just use types.ClassType instead of new.classobj, but still wonder what happens when we get to python 3.
