You're misusing __len__ here. If an object is iterable and also has a __len__, its __len__ should return the number of items you would get if you iterated over it. Anything else is confusing and can lead to trouble, as you found here.
But is there a cleaner way to do this?
Yes. Give up on using __len__ to get the length in bytes, and provide another way to do that. -- Greg -- https://mail.python.org/mailman/listinfo/python-list
