Removes unnecessarily verbose length comparisons
if len(list_of_hats) > 0: hat_to_wear = choose_hat(list_of_hats)
if list_of_hats: hat_to_wear = choose_hat(list_of_hats)
Something we often do is check whether a list or sequence has elements before we try and do something with it.
A Pythonic way of doing this is just to use the fact that Python lists and
sequences evaluate to
True if they have elements, and
Doing it this way is a convention, set out in Python's PEP8 style guide. Once you've gotten used to doing it this way it does make the code slightly easier to read and a bit less cluttered.
