Hi Colby,


Yes, this looks ok to me.  I think we can also express it as a
dictionary comprehension.
(https://docs.python.org/3/tutorial/datastructures.html#dictionaries)

    pt_table = {int(key): value for key, value in pt_table.items()}

I think the dictionary comprehension approach is slightly more
idiomatic, but what you've got looks ok too.
