Lists and arrays are important tools in programming. They let you keep track of groups of items. You can do many things with them. Let’s look at some of the basic actions you can take!

1. Making a List or Array

Creating a list or an array is easy.

• List Example: fruits = ["apple", "banana", "orange"]
• Array Example: numbers = [1, 2, 3, 4, 5]

2. Getting Items

You can get items from your list or array using their position, called an index. The count starts at 0.

• Example: To find the first fruit, you would use fruits[0], which gives you "apple".

3. Adding Items

You can add new items to your list or array.

• List: Use append(), like this: fruits.append("grape").
• Array: In some programming languages, you might need to create a bigger array to add items.

4. Taking Away Items

It’s easy to remove items too.

• List: Use remove(), like this: fruits.remove("banana").
• Array: You might need to make a new array that leaves out the item you want to remove.

5. Organizing Items

Sorting helps to put your items in order.

• Example: fruits.sort() sorts the list from A to Z.

6. Going Through Items

You can look at each item one by one using a for loop.

• Example:

for fruit in fruits:
    print(fruit)

These actions make lists and arrays great for handling data in programming!
