Lesson 3 of 20 · Sequences & Order
Sequences & Order — Part 11
Learn that order matters. Put steps in the right order. This is part 11 of 20.
What you'll learn
You will learn that code runs top to bottom in order, and that changing the order changes the result.
Steps
- 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!
