Lists and Functions
Using an element from a list in a function

Passing a list to a function will store it in the argument (just like with a string or a number!)

def first_item(items): print items[0] numbers = [2, 7, 9] first_item(numbers)
  1. In the example above, we define a function called first_item. It has one argument called items.
  2. Inside the function, we print out the item stored at index zero of items.
  3. After the function, we create a new list called numbers.
  4. Finally, we call the first_item function with numbers as its argument, which prints out 2.

Instructions

1.

Change line 2 so that list_function returns only the item stored in index one of x, rather than the entire x list.
