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

Last Updated : 29 Aug, 2025

turtle.down() method is used to lower the turtle’s pen, allowing it to draw as it moves. If the pen is already down, the turtle continues drawing.

**Syntax :

turtle.down()

# or

turtle.pendown()

# or

turtle.pd()

• **Parameters: This method does not require any arguments.
• **Returns: It only changes the pen state to “down” to enable drawing.

Examples

**Example 1: Basic use of pen up and down

Python `

import turtle

turtle.forward(50) turtle.up() turtle.forward(50) turtle.down() turtle.forward(50)

turtle.done()

`

Output:

**Explanation:

• The turtle draws the first 50 units.
• turtle.up() lifts the pen, so the next 50 units are moved without drawing.
• turtle.down() lowers the pen again, so the following 50 units are drawn.

**Example 2: Using pen up and down with turns

Python `

import turtle

turtle.forward(50) turtle.right(90) turtle.up() turtle.forward(50) turtle.down() turtle.right(90) turtle.forward(50)

turtle.done()

`

**Output:

**Explanation:

• The turtle draws the first segment, turns, and lifts the pen to move without drawing.
• After lowering the pen with turtle.down(), it resumes drawing the next segment, demonstrating how pen state controls what is drawn.
