Good question.

Try this:

import turtle
print(turtle.__file__)

That should print something like

'/usr/local/lib/python3.3/turtle.py'

or wherever you have installed Python to. If it is something like this:

/Users/Hershel/PycharmProjects/Project 1/turtle.py

then you have (accidentally) saved a new file called "turtle.py" and it 
is shadowing the standard library file and blocking it from being 
loading. Instead of importing the real turtle module, Python is 
importing your fake turtle module.

To fix that, delete or rename your turtle.py module, quit PyCharm, and 
start it up again.

Then you'll need to fix a small bug in your code:

Add round brackets (parentheses) to the pendown:

    turtle.pendown()

Without the brackets, it just names the function, it doesn't call it. In 
your case, it probably doesn't matter, since the turtle starts with the 
pen down by default.
