This is awesome

good job

good

I don't quite understand what extra piece this is asking for. Could someone explain a bit more explicitly? I have test 1 correct, but test 2 failed.

It's difficult to give much of a hint without giving away the answer. The key is that your function needs to be able to accept ANY input.

thats a tricky one. it really helps to improve coding practice.

Very very tricky problem

I suggest to make more description for your problem

I think that "Honey,do you think I'm wrong?" really is the one your wife need to ask,luckily,she seems bossy,not tricky.LOL

In test suit in two cases you showed but answer 'yes' not working

You need to make sure that the function can handle multiple inputs. It really goes to show you that you can't just accept what is given to you as is!
