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.")

Answer 2

You can try this code:

def shut_down(s):

if s =="yes":
    return "Shutting Down"

elif s =="no":
    return "Shutdown aborted"
else:
    return "Sorry"
print shut_down("yes")   

Answer 3

You can do it a couple of ways:

if s == 'Yes' or s == 'yes' or s == 'YES':
    return "Shutting down..."

Or:

if s in ['Yes', 'yes', 'YES']:
    return "Shutting down..."
