turtle.home() method moves the turtle back to the origin (0, 0) and sets its orientation to face east (0 degrees). This method is useful when you want to reset the turtle’s position and heading. It does not clear the drawing or reset other turtle properties.
Syntax
turtle.home()
- Parameters: This method takes no parameters.
- Returns: It only moves the turtle to the origin and resets its heading.
Example 1: Resetting Position and Heading
This example demonstrates how home() can reset the turtle’s position and orientation after moving and rotating.
import turtle
print(turtle.position())
turtle.forward(100)
print(turtle.position())
turtle.home()
print(turtle.position())
turtle.right(90)
turtle.forward(100)
print(turtle.position())
turtle.home()
print(turtle.position())
turtle.done()
Output
(0.0, 0.0)
(100.0, 0.0)
(0.0, 0.0)
(0.0, -100.0)
(0.0, 0.0)
Explanation:
- turtle.forward(100): Moves turtle in current heading (east by default).
- turtle.home(): Returns turtle to (0, 0) and faces east.
- turtle.right(90): Rotates turtle 90° clockwise (now facing south).
- Demonstrates how home() can be called multiple times to reset position and heading.
Example 2: Using home in Drawing Pattern
This example shows how home() can help in drawing repeated patterns by resetting the turtle to origin before each iteration.
import turtle
turtle.speed(10)
def draw_petal():
turtle.circle(50, 180)
turtle.right(90)
turtle.circle(50, 180)
for i in range(12):
draw_petal()
turtle.up()
turtle.home()
turtle.down()
turtle.left(30 * (i+1))
turtle.done()
Output
Explanation:
- draw_petal: Draws a semi-circular petal shape.
- turtle.up() and turtle.down(): Control pen to avoid unwanted lines.
- turtle.home(): Resets turtle to origin before drawing the next petal.
- turtle.left(30 * (i+1)): Rotates turtle so petals are evenly spaced (360° ÷ 12 = 30°).
- This creates a circular floral pattern centered at (0, 0).
