Turtles like Tina have a pen that draws when they move. We can tell them to pick the pen up, so that they can move without drawing a line. Then we can tell them to put the pen down, and they'll draw again. We tell them this with the `penup()` and `pendown()` commands.
```python.run
import turtle
tina = turtle.Turtle()
tina.shape('turtle')
tina.penup()
tina.goto(0,100)
tina.write("I don't draw when my pen is up!")
tina.goto(0,50)
tina.pendown()
tina.write("I do draw when my pen is down!")
tina.goto(-50,50)
```
