-Note that while `extend` maintains the "flat" structure of the list, appending a list to a list means
-the last element in `primes` will itself be a list, not an integer. Lists can contain values of any

+## Items can be removed from a list.
 
 - We use `del list_name[index]` to remove an element from a list (in the example, 9 is not a prime number) and thus shorten it.
