To make it clearer, I think you mean something like this::
def hand_rank(hand):
""" Determine the rank of the poker hand. """
rank = int(some_complex_computation(hand))
return rank
In other words, I'm assuming ‘hand_rank’ returns an integer.

This will return the item from the collection ‘hand’ with the maximum
value as determined by ‘hand_rank’. So this appears to do what you want.

This raises “TypeError: 'int' object is not iterable” because you're
operating on one return value from ‘hand_rank’, which is not a
collection.
