turtle.sety() function in Python (original) (raw)

Last Updated : 14 Aug, 2025

turtle.sety()method moves the turtle to a specified y-coordinate while keeping its current x-coordinate and heading (direction) unchanged. If the pen is down, it will draw a line from the current position to the new y-coordinate; if the pen is up, it moves without drawing.

**Syntax:

turtle.sety(y)

• **Parameters: y (int | float) is the y-coordinate to move the turtle to.
• **Returns: This method only changes the turtle's vertical position on the screen.

Examples of turtle.sety() function

**Example 1 : Simple vertical movement

Python `

import turtle

print(turtle.position()) # Initial position turtle.sety(30) print(turtle.position()) # After moving up turtle.sety(-50) print(turtle.position()) # After moving down

turtle.done()

`

**Output :

(0.0, 0.0)
(0.0, 30.0)
(0.0, -50.0)

**Explanation: The turtle’s y-coordinate changes to 30, then to -50, while the x-coordinate remains 0.

**Example 2 : Drawing with y-coordinate changes

Python `

import turtle

for i in range(4): turtle.forward(100) turtle.right(90) turtle.forward(20) turtle.right(90) turtle.forward(100)

turtle.penup()
turtle.sety(-40 * (i + 1))
turtle.pendown()

turtle.left(180)

turtle.done()

`

**Output

**Explanation: The turtle draws repeated vertical patterns, then uses sety() to jump down to the next row without affecting the x-coordinate.
