Python Turtle Graphics

What is the turtle library in Python?

turtle is a pre-installed Python library that enables users to create pictures and shapes by providing them with a virtual canvas.

The turtle module provides turtle graphics primitives, in both object-oriented and procedure-oriented ways. Because it uses Tkinter for the underlying graphics

How to Use turtle library to make graphics?

1. Install and import the library:
   pip install PythonTurtle (command for installation)
   import turtle (import at the top of project.py file)
2. Initialize the variable, which you’ll then use throughout the program to refer to the turtle:
   c=turtle.Turtle()
   you can use any variable instead of “c”.
3. Now, to open the turtle screen, you initialize a variable for it in the following way:
   c.getscreen()
   You should see a separate window open up

4. You can change the color of the window using the following command:
c.getscreen().bgcolor(“black”)

5. Changing the Screen Title:
c.title(“My Turtle Program”)

6. Changing the Turtle Shape:
c.shape(“turtle”)
c.shape(“arrow”)
c.shape(“circle”)

7. Change the color of the arrow referring turtle :
c.color(“color”)
e.g.
c.color(“red”,”yellow”)

Change speed:
c.speed(value)
e.g.
c.speed(15)

8 . Drawing Preset Figures:
c.circle(radius)
e.g.
c.circle(60)
Tou will get circle
c.dot(20)
you will get a filled dot

9. Moving the Turtle:

There are four directions that a turtle can move in:

• Forward
• Backward
• Left
• Right

Example :

c.right(90)

c.forward(100)

c.left(90)

c.backward(100)

You can use the shortened versions of these commands as well:

• c.rt() instead of c.right()
• c.fd() instead of c.forward()
• c.lt() instead of c.left()
• c.bk() instead of c.backward()

10. Filling in an Image:

c.begin_fill()
c.fd(100)
c.lt(120)
c.fd(100)
c.lt(120)
c.fd(100)
c.end_fill()
