turtle.backward() method moves the turtle backward by the specified distance (in pixels) from its current position, opposite to the direction it is facing. If the pen is down, it will draw a line while moving; if the pen is up, it will move without drawing.
Syntax:
turtle.backward(distance)
Parameters: distance (int | float) is the number of pixels to move backward.
Returns: This method only changes the turtle's position on the screen.
Examples
Example 1: Simple backward movement
import turtle
turtle.backward(100)
turtle.done()
Output:
Explanation: The turtle moves 100 pixels backward from its default starting direction, drawing a straight line.
Example 2: Backward with direction change
import turtle
turtle.backward(50)
turtle.right(90)
turtle.backward(50)
turtle.done()
Output:
Explanation: The turtle moves 50 pixels backward, turns right 90°, then moves another 50 pixels backward, forming an L-shaped path.
Example 3: Moving backward without drawing
import turtle
t = turtle.Turtle()
t.pendown()
t.backward(50)
t.penup()
t.backward(50)
turtle.done()
Output:
Explanation: The first backward movement draws a line, then the pen is lifted and the second movement leaves no trace.
