explicit is better than implicit ... so sure you could make it more consise
def __init__(self,a,b,c):
for k,v in locals().items():
if k != "self":
setattr(self,k,v)
the better question is should you ...
... that said if you want a named tuple I would recommend using a namedtuple (remember tuples have certain conditions attached to them) ... perhaps you want an ordereddict or even just a dict ...
