What should the output look like?
A rainbow flower-like pattern made of overlapping squares.
📖
How this works
Draw the same square 36 times, rotating a small 10° between each. Because 36 × 10° = 360°, the whole pattern sweeps through a full circle. The overlapping squares create a delicate flower-of-lines look — the classic spirograph.
Your turn — try these
- 1Change `range(36)` to `range(72)` and the rotation from `10` to `5`.
- 2Replace the square (4 sides × 90°) with a triangle (3 sides × 120°).
- 3Instead of squares, try pentagons: 5 sides, 72° per turn.
