While I agree that it's likely you're confusing Python objects and
names, Python *is* an interpreted language and therefore very flexible.
Here's a snippet showing one way to remove the 'redundancy'. (Be
forewarned that doing things like this is highly distasteful to some
people.)
### non-redundant example ###
import sys
class Pin:
def __init__(self, name, namespace=None):
self.name = name
if namespace == None:
# default to caller's globals
namespace = sys._getframe(1).f_globals
namespace[name] = self
Pin('aap') # create a Pin object named 'aap'
Pin('aap2') # create a Pin object named 'aap2'
print aap.name
print aap2.name
