Deprecated Lab — Trinket is shutting down

This lab was written for Trinket.io, which is shutting down in August 2026. The embedded trinket.io links on this page will stop working after that date.

These pages are kept for reference only. The current version of this course now runs every lab as an inline Skulpt editor right in the page — no account or install needed. Start at Chapter 1: Welcome to Python.

Python Turtle Graphics Stop Sign

In this lesson, we will use variables and for loop to draw a stop sign. We will also show how to use the penup, pendown, color, begin_fill, end_fill and write functions. Our write function will also change the font size using the font=("Arial", 30, "normal") parameter.

Sample Code

import turtle
dan = turtle.Turtle()
dan.shape('turtle')

distance = 50
sides = 8
# The angle we turn is related to the number of sides by this formula
angle = 360 / sides
my_color = "red"

dan.penup()
dan.goto(-50, 100)
dan.pendown()
dan.color(my_color)
dan.begin_fill()
# repeat the forward/right functions for each side
for i in range(sides):
   dan.forward(distance)
   dan.right(angle)

dan.end_fill()
dan.hideturtle()

dan.penup()
dan.right(110)
dan.forward(80)
dan.color('white')
dan.write('STOP', font=("Arial", 30, "normal"))
