Saw this a couple of days ago and is my new head canon.

When they report that the economy is great, always ask for whom…

Only if you have to rescue many princesses in a short period of time

I’m a delivery boy!

Rescuing is only I/O bounded; your argument is irrelevant.

Don’t forget to keep your return values…

rescued_princesses = [{"princess": princess, "rescued": princess.rescue()} for princess in [castle.get_princess() for castle in castles]]

Python:

from Rescues import Princess
Princess.rescue()
