That's where PJE's more generic approach comes in:
def initialize(ob, args, excluded=['self']):
for k in excluded:
if k in args:
del args[k]
for k, v in args.items():
setattr(ob,k,v)
class grouping:
def __init__(self, x, y, z):
initialize(self, locals())
Or, one could have a look at the 'namespace' module, which came out of
the last pre-PEP covering this kind of area:
http://namespace.python-hosting.com/
'Record' is particularly interesting from an auto-initialisation point
of view (the class attributes define the expected instance
attributes). Although I may be a little biased, since I wrote that
class. . .
Cheers,
Nick.
