Hey, I see how the example shows it like this, but you're actually supposed to complete it a different way. You want it to all be part of one function; the shut_down function, so all of the if/elif/else statements would be inside of shut_down. Also, Yes() and No() aren't functions, so you will have to evalutate whether the argument, (s) is equal to the strings yes and no.
From the instructions:
shut_down function receives an
s equal to "yes", it should
return "Shutting down"
sis equal to "no", then the function should
return "Shutdown aborted".
shut_down gets anything other than those inputs, the function should
Can you start this and then ask me more specific questions about what you're having trouble with? i want to see how for you can get by yourself
