This seems like a really REALLY bad idea. You're putting a lot of work
into your __del__ function, and that's not getting called until
everything's shutting down. (Also, xrange doesn't exist, hence the
"exception ignored" thing.)
Avoid putting this sort of work into __del__ by explicitly marking
that you're done with the object. A context manager is a good choice
here.
