Question

Hi all, I am working on the review in "functions" -- unit 4 in codecademy and I seem to be stuck. Any help would be great. Thanks.

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

Probably something stupid but I'm a newbie at this.

Answer 1

Unless you created/imported a function named "lower()" that takes a string, I'd say that was part of your issue. What is the error you're getting?

Answer 2

lower() is a built-in function of the string class, so to use it you would employ the dot notation.
s.lower()

Since you have a string that you are evaluating you will only be able to compare that to a string. This means that your entries similar to the line
if lower(s) == yes:
must in fact be changed to
if s.lower() == "yes": OR if s.lower() == 'yes':

Answer 3

Thanks .... That was it. Being a newbie can be quite frustrating. Thanks again.

Answer 4

You're welcome.
