turtle.penup

As an AI language model, I cannot perform physical actions like a turtle does. However, I can provide you with information about the `turtle.penup()` function in Python.

`turtle.penup()` is a function in the turtle module of Python that is used to lift the pen off the canvas. When the pen is lifted, the turtle can move without leaving a trail behind it. This function is often used to move the turtle to a new location without drawing anything, or to start drawing a new shape from a different position.

Here is an example code snippet that demonstrates the use of `turtle.penup()`:

import turtle

# create a turtle object
t = turtle.Turtle()

# move the turtle without drawing
t.penup()
t.goto(100, 100)

# start drawing a new shape
t.pendown()
t.circle(50)

# exit the turtle graphics window
turtle.exitonclick()

In this example, the turtle object `t` is first created using the `turtle.Turtle()` function. The `t.penup()` function is then called to lift the pen off the canvas, and the `t.goto(100, 100)` function is used to move the turtle to the position (100, 100) without drawing anything. The `t.pendown()` function is then called to lower the pen back onto the canvas, and the `t.circle(50)` function is used to draw a circle with a radius of 50 units. Finally, the `turtle.exitonclick()` function is called to exit the turtle graphics window when the user clicks on it.
