*** Video Description ***
In this Scratch 3 basics tutorial, we follow on from the previous tutorial on variables to help our understanding of lists. Essentially, lists are just a bunch of variables group together. We use the idea of a street with houses on it to understand variables. A street has a name, which is the same as the name for a list. Each street has a house on it and each list has a place for a variable. Each house has a number so that we can locate it. Each list item has a position so that we can locate it as well. We also go through each block that we can use for lists including: how to add an item to a list, how to delete an item in a list, how to add an item at a position, how to delete an item at a position, how to get the value of an item and how to check if an item is in our list.

Thank you really much! It helped me a lot! I learn Python, HTML and C++. In Python lists are called “lists” too, but you can use “Tuples” and “sets”. But I have a question: For what can you use lists in Scratch? Thanks for an answer in advance! Best regards!😊😊

Wow, you are good making tutorials, i dont know why you not have more subsuribers!

avbergman

you under explained everything. I've been trying to figure out how to use lists for a while now and I don't think there is a video on YouTube that can do it the right way

Hi! Can we influence how many lines of the list are shown at a certain moment? For ex. I need to show the superpowers gained just at the levels of a game so far
Using several lists for that would increase the code too much

Thanks for sharing! Is it possible to store sounds or costumes in a list? I'm trying to create a speaking clock (which speaks out the time) but using 100 if statements is no fun and makes the project meaningless.

Fanally someone who dowsn't just have begginers, but also advanced tutoriels on something, but I have to start with the basics first

I can't find <<item [dropdown option] of "list">> in 3.0. It is in a Scratch Wiki, but I don't see it on this video and I don't have it in my projects. I asked on the Scratch Discussion page, but the only response I have gotten so far is that it is still there. That doesn't help. Where is it? I also notice in the wiki that there is a <<delete [dropdown option] of "list>> but not on my project. The wiki specifically says <<item [last] of "list">> and <<delete [last] of "list">> with [last] having a dropdown option. Please help. I am making a chatbot for a masters AI class and it would help to have the blocks according to the Wiki.

I'm having trouble to add a specific amount of items on my list eg: repeat 10 times, add item (thing) to list. It keeps adding less then I coded it to, is there a way to fix this?
