Turtle is a special feathers of Python. Using Turtle, we can easily draw in a drawing board.
First we import the turtle module. Then create a window, next we create turtle object and using turtle method we can draw in the drawing board.
Some turtle method
| METHOD | PARAMETER | DESCRIPTION |
|---|---|---|
| Turtle() | None | It creates and returns a new turtle object |
| forward() | amount | It moves the turtle forward by the specified amount |
| backward() | amount | It moves the turtle backward by the specified amount |
| right() | angle | It turns the turtle clockwise |
| left() | angle | It turns the turtle counter clockwise |
| penup() | None | It picks up the turtle’s Pen |
| pendown() | None | Puts down the turtle’s Pen |
| up() | None | Picks up the turtle’s Pen |
| down() | None | Puts down the turtle’s Pen |
| color() | Color name | Changes the color of the turtle’s pen |
| fillcolor() | Color name | Changes the color of the turtle will use to fill a polygon |
| heading() | None | It returns the current heading |
| position() | None | It returns the current position |
| goto() | x, y | It moves the turtle to position x,y |
| begin_fill() | None | Remember the starting point for a filled polygon |
| end_fill() | None | It closes the polygon and fills with the current fill color |
| dot() | None | Leaves the dot at the current position |
| stamp() | None | Leaves an impression of a turtle shape at the current location |
| shape() | shapename | Should be ‘arrow’, ‘classic’, ‘turtle’ or ‘circle’ |
Example code
# import turtle library
import turtle
my_window = turtle.Screen()
my_window.bgcolor("blue") # creates a graphics window
my_pen = turtle.Turtle()
my_pen.forward(150)
my_pen.left(90)
my_pen.forward(75)
my_pen.color("white")
my_pen.pensize(12)
Output
Draw a Square
Example code
# import turtle library import turtle my_pen = turtle.Turtle() for i in range(4): my_pen.forward(50) my_pen.right(90) turtle.done()
Output
Draw a star
Example code
# import turtle library import turtle my_pen = turtle.Turtle() for i in range(50): my_pen.forward(50) my_pen.right(144) turtle.done()
Output
Draw a Hexagon
Example code
# import turtle library import turtle polygon = turtle.Turtle() my_num_sides = 6 my_side_length = 70 my_angle = 360.0 / my_num_sides for i in range(my_num_sides): polygon.forward(my_side_length) polygon.right(my_angle) turtle.done()
Output
Draw a square inside another square box.
Example code
# import turtle library
import turtle
my_wn = turtle.Screen()
my_wn.bgcolor("light blue")
my_wn.title("Turtle")
my_pen = turtle.Turtle()
my_pen.color("black")
def my_sqrfunc(size):
for i in range(4):
my_pen.fd(size)
my_pen.left(90)
size = size - 5
my_sqrfunc(146)
my_sqrfunc(126)
my_sqrfunc(106)
my_sqrfunc(86)
my_sqrfunc(66)
my_sqrfunc(46)
my_sqrfunc(26)
Output
Drawing of another pattern
Example code
# import turtle library import turtle my_wn = turtle.Screen() turtle.speed(2) for i in range(30): turtle.circle(5*i) turtle.circle(-5*i) turtle.left(i) turtle.exitonclick()
Output
Drawing of another pattern
Example code
# import turtle library
import turtle
colors = [ "red","purple","blue","green","orange","yellow"]
my_pen = turtle.Pen()
turtle.bgcolor("black")
for x in range(360):
my_pen.pencolor(colors[x % 6])
my_pen.width(x/100 + 1)
my_pen.forward(x)
my_pen.left(59)
Output
