I copied your code between the hash lines and get this:

   File "my_turtle.py", line 19
     if (abs(turtle.position()[0])>  turtle.window_height()/2) or
                                                                ^
SyntaxError: invalid syntax


Is that all of your code?  it seems to be cut off


Do you see it now?  Your reply contained the 10 ten lines or so of code 
that follows.
