Lists — Part 7
Store many items in a list. This is part 7 of 20.
What you'll learn
You will learn that lists store multiple values, and you access them by their index (starting at 0).
Steps
- 1A list holds multiple values in order. Here, items contains three fruits: apple, banana, orange.
- 2items[0] means 'the first item'. In coding, we count from 0! So items[0] is 'apple', items[1] is 'banana', items[2] is 'orange'.
- 3Lists are super useful — think of a playlist (list of songs), a shopping list, or a leaderboard (list of scores).
- 4You can add items, remove items, and check how many items are in a list with len(). Lists grow and shrink as needed!
