We can add new items to the list using the append instruction.

This is a little different from functions we've seen so far.

The append instruction is actually a function, but only a function that works on lists.

Since it only works on lists, it is called on a list using a dot or full-stop character.

Lists have lots of other operations, I'll list a few here but there many more.

remove

Remove an item from the list.

extend

Combine two lists

insert

Insert adds a new item to the list, but places it in a specific index. This 'pushes' all the items after it, increasing their index by one.

index

Get the index of an item.

copy

The copy instruction makes a new list with all the same items. This is an important instrucion, as all the operations we do change the values in the list. Sometimes you want to keep the list intact and perform operations on it.
