The instructions say this function "returns the first four items from whatever iterable is given to it." So...

  • when they say "given to it", they mean it should have a parameter
  • the parameter name should go between the parentheses on the first line
  • the function definition should start with the "def" keyword
  • you won't need to assign anything with static data
  • the "stop" value of a slice should be one higher than the index of the last item you want
