What you will learn

See real-life uses of lists — scores, names, prices.

In simple words

Lists shine when you have many similar things: exam scores, product prices, guest names.

Think of it like this

Class test marks written in a column — average, highest, lowest are easy to loop over.

Ways to store many values together — shopping lists, contacts, unique items.

Easy example — try this first

Easy example — run this first. Change values and press Run again.
