you're close. the variable you need to switch on is key, not world. depending on what key is, you append value to the various lists. then that means each case is only for the key, not key value. so in the case of a certain key, do whatever with the corresponding value. here you append the value to a given list. then you just need a case for each key and a default and whatever else the challenge asks for.
