There is something very suspicious about this line: I just tried this in
the interpreter, and:
>>> for c in range[1, 6]:
... print c
Traceback (most recent call last):
File "<stdin>", line 1, in ?
TypeError: unsubscriptable object
And this fits closely with the TypeError message that you were getting:
> TypeError: unsubscriptable object
.... since your error message
still looked very strange to me. Hmmm... Try to fix the subscripting
problem above, and see if that clears things up for you.
I think this is the whole story. The error-message means - in my opinion -
that range is not a subscriptable object:
subscription means getting acces to an element of some compund data object
via an index,
as is possible for strings, lists etc. This is of course not possible for a
built-in functin as range()
(but this is what you tried by range)

hope that "clears things up"
