I had tried that, but I was concerned that it returned a None, so I thought there was no way to refer to the screen after using it. Trying it again, it seems: import turtle turtle.setup(800, 600) wn = turtle.Screen() alex = turtle.Turtle() alex.forward(200) wn.exitonclick() works just fine.

Hi All,

I'm working on an introductory CS book using Python with the turtle module, but I'm finding the inability of turtle.Screen() to take screen size arguments to be a real pain.  The screen size appears to depend on the screen size of the host environment, which means standardizing screen shots for the book becomes impossible.

Any thoughts on this issue?  It would be a huge help in promoting Python's use in education if we could make use of such a potentially fine module as the turtle module, but I'm finding it very difficult to write curriculum materials that use it since students don't have control over the turtle's screen in any easy to use way.

Thanks!

I believe you want turtle.setup, http://docs.python.org/library/turtle.html#turtle.setup
