Oops, try again. Your function failed on the message yes. It returned 'Sorry' when it should have returned 'Shutting down'
It should be returning 'Shutting Down' instead of 'Sorry'
def shut_down(s): if s == 'Yes': return 'Shutting down' elif s == 'No': return 'Shutdown aborted' else: return 'Sorry' shut_down('Yes')
