Question
In python, if you have sequence (i.e. list), named s, how would you get the value in that sequence with the minimum length (e.g. for l = ["one", "athree", "zero"], "one" would be returned)?
Answer
min(s, key=len)

For Aristotle, there is an active reason which makes objects of thought.
A passive reason receives, combines and compares the objects of thought.
