Functions and if - else in python. Mutliple conditions. Codeacademy

Question

Write a function, shut_down, that takes one parameter (you can use anything you like; in this case, we\'d use s for string).

The shut_down func

Answer 1

def shut_down(s):
    return ("Shutting down..." if s in("Yes","yes","YES")
            else "Shutdown aborted!" if s in ("No","no","NO")
            else "Sorry, I didn't understand you.")

GordonsBeard's idea is a good one. Probably "yEs" and "yES" etc are acceptable criteria;
Then I propose in this case:

def shut_down(s,d = {'yes':"Shutting down...",'no':"Shutdown aborted!"}):
    return d.get(s.lower(),"Sorry, I didn't understand you.")
