What is the size of the Python Turtle window in pixels?

Question

I used the function screensize() and it told me that my window was (400, 300). I need to get to the top left hand corner to draw some stuff, but when I put in (-400, 300), my turtle goes way off the window. Is there any other function I can use to get the size of my turtle window?

• Mike67: I think by default, the screen center is (0,0). The top left corner is (-200, 150). At x = -400 the turtle is 200 pixels left of the screen.

Answer 1

The point 0, 0 is in the center of the screen, so if you want to go to the top left corner, you need to use turtle.goto(200, 150). A problem also could be that if you used setup() to create the window, screensize() will return the default, which is (400, 300), even if you screen is bigger.
