The turtle.left() function in Python rotates the turtle counter-clockwise (left) by a specified angle. This only changes the turtle’s heading, not its position.

Syntax: turtle.left(angle)
Parameters: angle: a number (integer or float) representing the degrees to turn.

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

Demo3.py

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

import turtle

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

t.forward(100)
t.left(90)      # Turn left 90 degrees
t.forward(100)

window.exitonclick()

The following is the output:

turtle.left() in Python Turtle

In the above code, we followed the below steps:

Import the module: import turtle loads Python’s turtle graphics library so you can draw with a virtual “pen.”
Create the screen: window = turtle.Screen() opens the drawing window where movement is shown.
Create the turtle: t = turtle.Turtle() creates a turtle object you’ll control.
Move forward:forward(100) moves the turtle 100 units in its current direction, drawing a line.
Turn left:left(90) rotates the turtle 90 degrees counterclockwise without moving.
Move forward again:forward(100) draws another 100-unit line in the new direction, forming an “L” shape.
Close on click:exitonclick() keeps the window open until you click inside it, then closes.
