I'm not sure what you're getting at, but have you tried this:

class A(object):
def __getitem__(sel f, ky):
return self.__dict__[ky]

for example:[color=blue][color=green][color=darkred]
>>> class A(object):[/color][/color][/color]
def __init__(self,a ,b,c):
self.a = a
self.b = b
self.c = c
def __getitem__(sel f, ky):
return self.__dict__[ky]

[color=blue][color=green][color=darkred]
>>> a = A(1,2,3)
>>> a['a'][/color][/color][/color]
1[color=blue][color=green][color=darkred]
>>> a['b'][/color][/color][/color]
2[color=blue][color=green][color=darkred]
>>>[/color][/color][/color]
