18 Sep turtle.isdown() function in Python

The turtle.isdown() function returns True if the pen is down, False if it is up. Used to check the current state of the pen.

Syntax: turtle.isdown()
Parameters: None.

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

Demo20.py

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

import turtle

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

print("Pen is down:", t.isdown())  # Check if pen is down
t.penup()
print("Pen is down:", t.isdown())  # Check again

window.exitonclick()

The following is the output:

In the above code, we followed the below steps:

1. Import the module: import turtle loads Python’s turtle graphics library.
2. Create the screen: window = turtle.Screen() opens the drawing window.
3. Create the turtle: t = turtle.Turtle() creates the turtle (your pen).
4. Check initial pen state: print(“Pen is down:”, t.isdown()) prints whether the pen is down. By default, this is True, meaning movements would draw.
5. Lift the pen: t.penup() raises the pen so movements won’t draw.
6. Check again: print(“Pen is down:”, t.isdown()) prints the updated state, which is now False.

Close on click: window.exitonclick() keeps the window open until you click, then closes.
