What Are Lists?

You’ve been working with single values so far:

weapon = "Sword"
potion = "Health Potion"
gold = 50

That works… until your player picks up five items, three keys, two potions, and a mysterious banana.

Suddenly, a bunch of separate variables feels like trying to carry loot with no backpack.

Enter Lists

A list is a way to store multiple values in a single variable.

inventory = ["Sword", "Health Potion", "Key", "Banana"]
print(inventory)

Now inventory is your backpack in code form.

• Square brackets [] mean “this is a list”
• Items are separated by commas
• Each item has a position (index) in the list

Indexing: Python Starts at 0 (Because Of Course It Does)

inventory = ["Sword", "Health Potion", "Key", "Banana"]

print(inventory[0])   # Sword
print(inventory[1])   # Health Potion
print(inventory[2])   # Key
print(inventory[3])   # Banana

Python counts like:

• 0 → first item
• 1 → second item
• 2 → third item

It’s weird at first, then it becomes normal… like most of programming.

Why Lists Matter for Games

Lists let you:

• store all items in your inventory
• keep track of enemies in a level
• store dialogue lines
• manage quests, levels, loot drops

Instead of writing:

enemy1 = "Goblin"
enemy2 = "Orc"
enemy3 = "Slime"

You can write:

enemies = ["Goblin", "Orc", "Slime"]
print(enemies)

Much cleaner. Much more real developer.

You just built your first weapon list.

Your game officially has a tiny armory.
