A data structure used to store an ordered collection of values, like numbers, text, or other lists.

Add a new item to the end of an existing list.

Remove an item from a specific position within a list.

Change the value of an item at a specific position in a list.

Retrieve the number of items included in a list.

Get a specific item from a list using its position (index).

Access the first item of a list.

Access the last item of a list.

Iterate (repeat) a block of code for each item in a list.

Execute a block of code repeatedly until a specific condition is met.

A collection of items stored in a specific order. Think of it like a shopping list where each item has a place.

This block allows you to create a new list, like starting a fresh shopping list.

Each item in a list has a unique position called an index. The first item has an index of 0. It's like assigning house numbers to items in a street!

This handy block helps you access an item at a specific index in the list. It's like finding an item in your shopping list by its number.

This block allows you to add a new item at the end of the list. It's like adding a new item to your shopping list after you've already filled the basket.

This block removes an item from the list based on its index. It's like crossing out an item from your shopping list that you don't need anymore.

This block allows you to change the value of an existing item at a specific index. It's like replacing one item in your shopping list with another.

This block tells you how many items are in a list. Think of it like checking the number of items you have in your shopping cart.

This loop allows you to process each item in a list, like going through every item on your shopping list one by one.

This loop repeats a block of code as long as a specific condition is true. It’s like repeatedly checking if you have everything on your shopping list until you've got it all.

Creating a list in Blockly involves using a specific block to initiate the list and then adding items to it.

Each item in a list has a unique position called an index, starting from 0. Using the index, you can access any specific item in the list.

You can retrieve the first or last item in a list directly using dedicated blocks. This simplifies accessing these specific items.

Using 'append item to list', you add a new item to the end of the existing list, just like adding something to a shopping bag.

To remove an item from a list, you specify the index of the item you want to remove, effectively taking it out of the list.

You can change the value of any existing item in a list by using its index and updating it with a new value.

The 'length of list' block tells you how many items are currently in the list. It's like counting the items in your shopping basket.

A 'for each item in list' loop iterates through each item in a list, executing the code block for every item. Think of going through every item on your shopping list one by one.

A 'while' loop repeatedly executes a block of code until a condition becomes true. It's like checking your shopping list until you've got everything.

Lists are a powerful way to store and manage data in Blockly. By understanding how to create, access, and manipulate lists, you can build more complex programs.
