The turtle.up() or turtle.penup() function lifts the pen up. When the pen is up, the turtle can move without drawing a line.

Syntax: turtle.penup() or turtle.up()
Parameters: None.

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

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

import turtle

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

t.forward(50)   # Draws a line
t.penup()       # Lift the pen up (stop drawing)
t.forward(50)   # Moves without drawing
t.pendown()     # Put the pen down (start drawing again)
t.forward(50)   # Draws a line again

window.exitonclick()

The following is the output:

turtle.penup() function in Python

In the above code, we followed the below steps:

Import the module: import turtle loads Python’s turtle graphics library.
Create the screen: window = turtle.Screen() opens the drawing window.
Create the turtle: t = turtle.Turtle() creates the turtle (your pen).
Draw first segment: t.forward(50) moves 50 units forward, drawing a line because the pen is down by default.
Lift the pen: t.penup() raises the pen so movements won’t draw.
Move without drawing: t.forward(50) advances 50 units with no line since the pen is up.
Lower the pen: t.pendown() puts the pen back down to resume drawing.
Draw second segment: t.forward(50) draws another 50-unit line.
Close on click: window.exitonclick() keeps the window open until you click, then closes.
