Make Something — Part 4

Use imagination to create.

What you'll learn

You will learn that code runs top to bottom in order, and that changing the order changes the result.

Words to know

Sequence: A list of steps that happen one after another in order.
Order: The sequence in which steps run. Changing the order can change the result.
print(): A command that shows a message on the screen.

Press ▶ Run and see what the computer says!

1Read the code above. Notice how each print() is on its own line — the computer reads them top to bottom, one after another.
2The output would be: Step 1, Step 2, Step 3, Done! — in that exact order. The order of lines decides the order of output.
3Imagine swapping Step 2 and Step 3. The output would change! In a sequence, order matters.
4A sequence is a list of instructions in order. Every program is built from sequences. You just learned the most basic building block of coding!

Auto-run is on: change the code and the result updates by itself.
