Robert's Coding Course

What's a Variable?

A variable is a name that stores a value. Create variables.py: name = "Robert" age = 11 print(name) print(age) ⚠️ Watch Out = does NOT mean "equals" in Python. It means "store this value." Think of it as an arrow: name ← "Robert"

What's a List?

A variable holds one thing. A list holds a bunch of things in order. Create lists.py: fruits = ["apple", "banana", "cherry"] print(fruits) Square brackets [] make a list. Commas separate the items.

What's Wrong with the Old Version?

In the last lesson, chips just appeared in place -- poof! That works, but it doesn't look like a real Connect 4 game. In the real game, you drop a chip in the top and it falls down to the bottom. Let's make that happen.

Why Classes?

Look at the Snake code from last lesson. The snake's data (snake, snake_direction) and the snake's behavior (movement, collision checking, drawing) are scattered all over the place. The apple's stuff is mixed in too. It works, but it's messy.

Why Multiple Rooms?

Right now our dungeon is one big open area. But real dungeon crawlers have rooms you move between — each room is its own mini-challenge. Think of it like floors in Minecraft Dungeons, except we're using doors instead of staircases.
