slices

The instructions say to "create a function named first_4 that returns the first four items from whatever iterable is given to it.". Using a slice is a good idea, but:

• you need a function (not a variable) named "first_4"
• function definitions start with "def"
• the function will use a parameter to get the data, you won't need to provide any literals
• you will want to add a "stop" value to the slice to make sure it only takes 4 items
• remember to return the resuts
