Code comments are good and all, but there's a time and a place for them. They're more or less an opinionated free-form version of what code is doing.

In a library, they're good for documentation. However in a platform, it makes less sense. Especially one which is changing at quite a fast rate (though it has matured in recent months).

Dont get me wrong, we aren't doing wades of horrible, unintelligible code. We need to be sure of what happens when we call a function, so we make sure the signature is always correct.

def do_good_things(puppies): # "good things" is opinionated. Say what you're doing
"""give treats to puppies""" # doc string is wrong
pet(puppies)
