Identifying that a variable is a new-style class in Python?
- by Dave Johansen
I'm using Python 2.x and I'm wondering if there's a way to tell if a variable is a new-style class? I know that if it's an old-style class that I can do the following to find out.
import types
class oldclass:
pass
def test():
o = oldclass()
if type(o) is types.InstanceType:
print 'Is old-style'
else:
print 'Is NOT old-style'
…
