Question

you created a pen as an instance of turtle. you drew a line. what does the following line do?
up()
moves all drawings one step up
\lifts\ the pen so you can move it without drawing
moves the pen one step up
points the pen so it is pointing straight up

Explanation:

In the Python turtle module, the up() method (also known as penup()) is used to lift the pen. When the pen is lifted, moving the turtle (which acts as the "pen" in this drawing context) will not leave a mark (i.e., will not draw) on the screen. It has nothing to do with moving all drawings, moving the pen a specific "step" up in a coordinate - like sense, or changing the pen's pointing direction.

Answer:

"lifts" the pen so you can move it without drawing
