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

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

for example:
 >>> class A(object):
	def __init__(self,a,b,c):
		self.a = a
		self.b = b
		self.c = c
	def __getitem__(self, ky):
		return self.__dict__[ky]

	
 >>> a = A(1,2,3)
 >>> a['a']
1
 >>> a['b']
2
