The turtle.seth() function in Python sets the turtle’s heading (direction it is facing) to the specified angle. 0 is east, 90 is north, 180 is west, 270 is south.

Syntax: turtle.seth(to_angle)
Parameters: to_angle: a number (integer or float) representing the new heading in degrees.

Let us see an example to implement the turtle.seth() function in Python:

Demo7.py

# turtle.seth() function in Python
# Code by Studyopedia

import turtle

window = turtle.Screen()
t = turtle.Turtle()

t.seth(45)      # Set heading to 45 degrees (northeast)
t.forward(100)
t.seth(180)     # Set heading to 180 degrees (west)
t.forward(100)

window.exitonclick()

The following is the output:

In the above code, we followed the below steps:

Import the module: import turtle loads Python’s turtle graphics library for drawing.
Create the screen: window = turtle.Screen() opens the drawing window.
Create the turtle: t = turtle.Turtle() creates the turtle (the pen) you’ll control.
Set absolute heading to 45°: t.seth(45) points the turtle northeast. This rotates without moving; headings are absolute (0° east, 90° north, 180° west, 270° south).
Move forward 100: t.forward(100) draws a 100-unit line along the 45° direction.
Set absolute heading to 180°: t.seth(180) reorients the turtle to face west, again without moving its position.
Move forward 100: t.forward(100) draws a 100-unit line to the left from the current point.
Close on click: window.exitonclick() keeps the window open until you click inside it, then closes.
