'class' named tuple

[Emmanuel Mayssat]

I have the following program.
I am trying to have index the attributes of an object using __getitem__.
Reading them this way works great, but assigning them a value doesn't
Is there a way to do such a thing?
(Almost like a named tuple, but with custom methods)

class LIter(object):
def __init__(self,parent=None):
super(LIter, self).__init__()
self.toto = 3
self.tata = 'terto'

def __getitem__(self,index):
if index == 0 : return self.toto
if index == 1 : return self.tata

# [other methods]



if __name__ == "__main__":
i = LIter()
print i[0]
print i[1]
i.toto = 2
i.tata = 'bye'
print i[0]
print i[1]
i[0] = -1
i[1] = 'salut'
print i[0]
print i[1]





$ python iter.py
3
terto
2
bye
