I type everything in that other posts have suggested to move forward on lessons, however it just returns:
Oops, try again. Your function failed on the message yes. It returned 'Sorry' when it should have returned 'Shutting down'
I expect it to return "Shutting down"
Replace this line with your code. def shut_down(s): if s == "Yes": return "Shutting down" elif s == "no": return "Shutdown aborted" else: return "Sorry" shut_down("Yes")
