A list is a collection of items. A list is ordered, meaning that each item has a specific position in the list.

We can declare that the data is a list using square brackets []. Between the square brackets are the items, each item is separated by a comma.

The following code creates a list, assigns it to the variable names.

The value alice is in the first position, also known as index 0. When we're coding, we almost always count the first item as the 0 index. This creates a lot of confusion in the beginning but eventually you get used to it.

We can have duplicates in the list, and we can use other types of data too.

Each item in a list has an index, we can use this index to get or set the item at that position. The instruction to get an item from a list at a postion is this

item = list[index]

And here's an example

And the instruction to set the item at an index is like setting a variable.
