That documentation on PyLint is atrocious!
From my reading of it, at the beginning of your file, you put a
comment something like
# pylint: disable-msg=W0612
which should disable that particular message. Totally untested.
I don't know if PyLint is smart enough, but if you don't use "i",
you might use the common "throwaway" variable of "_":
for _ in xrange(10):
in which case it _might_ recognize that it's a throwaway variable
and not warn you about it. At least that would be nice of it.
But given the abusive nature of the documenation, I'm not sure
that's the case ;)
