penup -- Command, no inputs. Abbreviation: pu
This command tells the turtle to raise its pen from the paper, so that
it does not leave a trace when it moves. In the case of the display
turtle, there is no physical pen to move mechanically, but the effect
is the same: any forward or back commands after this point do not draw
a line. The floor turtle starts with its pen up; the display turtle
starts with its pen down. Note: the floor turtle will not move on the
carpet correctly with its pen down; put it on a smooth surface if you
want to draw pictures.
