If your list is a jumbled mess, you may need to sort() it.

animals = ["cat", "ant", "bat"]
animals.sort()

for animal in animals:
  print animal

1. First, we create a list called animals with three strings. The strings are not in alphabetical order.
2. Then, we sort animals into alphabetical order. Note that .sort() modifies the list rather than returning a new list.
3. Then, for each item in animals, we print that item out as "ant", "bat", "cat" on their own line each.
