Unlock Python Turtle: Master Basic Drawing Commands in Minutes

Hello, everyone. I'm a Python enthusiast.

Introduction

When you draw with code, it can feel tricky; today we introduce the magical drawing module turtle . It lets the pen move freely with simple commands, making graphics creation intuitive.

Importing the Module

import turtle

Basic Turtle Usage

1. Set Canvas Size

To draw, you need a canvas. Use the following command to set its width, height, and background color:

turtle.screensize(width, height, color)  # set width, height, color

2. Set Canvas Coordinates

Configure the window's position on the screen:

turtle.setup(width, height, startx, starty)  # set width, height, start x, start y

3. Show Main Window

Like Tkinter, you need mainloop() to display the window:

import turtle
turtle.Screen().title('Drawing Tool')  # set window title
turtle.screensize(400, 400, "red")  # canvas size and background color
turtle.setup(width=600, height=600, startx=300, starty=50)  # window size and position
turtle.mainloop()  # display the main window

4. Configure the Pen

Create a pen and set its size and color:

turtle.pencolor('green')  # set pen color to green (default is black)
turtle.pensize(1)        # set pen size
turtle.speed()           # set pen speed (range 0-10)

This creates the first arrow; the turtle draws by moving this arrow.

5. Basic Drawing Commands

1. Forward

turtle.forward(100)  # move forward 100 pixels
turtle.fd(100)

2. Backward

turtle.backward(200)  # move backward 200 pixels
turtle.back(200)
turtle.bk(200)

3. Go To

turtle.goto(100, 200)      # move directly to (100,200)
turtle.setpos(100, 200)
turtle.setposition(100, 200)

4. Left

turtle.left(50)   # turn left 50 degrees
turtle.lt(50)

5. Right

turtle.right(60)  # turn right 60 degrees
turtle.rt(60)

6. Pen Up (Prepare to Move)

turtle.penup()

7. Pen Down (Resume Drawing)

turtle.pendown()

8. Draw Circle

turtle.circle(radius, extent, steps)  # draw a circle
turtle.dot(int)  # also draws a dot

9. Move Along X Axis

turtle.setx(100)  # move 100 pixels on X axis

10. Move Along Y Axis

turtle.sety(100)  # move 100 pixels on Y axis

11. Set Heading Angle

turtle.setheading(90)  # set current angle to 90 degrees
turtle.seth(90)

12. Return Home

turtle.home()

Below is a complete script demonstrating these commands and showing the turtle's trajectory:

import turtle
import time
t = turtle.Pen()
t.shape('turtle')
t.pencolor('green')
turtle.bgcolor('gray')
t.width = 3
time.sleep(1)
t.penup()  # prepare to move
t.forward(100)  # forward 100
time.sleep(1)
t.backward(200)  # backward 200
time.sleep(1)
t.goto(100, 200)  # go to (100,200)
time.sleep(1)
t.left(50)  # left 50
time.sleep(1)
t.right(60)  # right 60
time.sleep(1)
t.penup()  # prepare to move
t.setx(100)  # move on X
time.sleep(1)
t.sety(100)  # move on Y
turtle.seth(90)
turtle.home()
turtle.mainloop()  # keep window open

The turtle's path can also be visualized:

Additional Commands

13. Stamp (Copy Current Shape)

14. Clear Stamps

turtle.clearstamp()

15. Clear All Stamps

turtle.clearstamps()

16. Undo

turtle.undo()

17. Get Position

turtle.position()
# or turtle.pos()

18. Angle to a Point

turtle.towards(x, y)

19. X Coordinate

turtle.xcor()

20. Y Coordinate

turtle.ycor()

21. Heading

turtle.heading()

22. Distance to a Point

turtle.distance(x, y)

23. Clear Drawing (Keep Turtle State)

turtle.clear()
# or turtle.clearscreen()

24. Reset (Clear and Reset State)

turtle.reset()
# or turtle.resetscreen()

25. Visibility Check

turtle.isvisible()

26. Write Text

turtle.write(text, font)

27. Fill Color

turtle.fillcolor('red')

28. Pen Down Check

turtle.isdown()  # note: no isup() method

29. Hide Turtle

# or turtle.ht()

30. Show Turtle

turtle.showturtle()
# or turtle.st()

31. Begin Fill

turtle.begin_fill()

32. End Fill

# or turtle.done

36. Set Mode

turtle.mode('standard')  # counter‑clockwise
# or 'world' for clockwise

37. Set Drawing Delay (ms)

turtle.delay(delay=None)

38. Record Polygon Vertices

turtle.begin_poly()
# draw shape
turtle.end_poly()
poly = turtle.get_poly()
