Python Turtle Set Bildschirmgröße
Let's clear up some misconceptions about turtle window size:
First, the default window you get in standalone turtle is 50% of your
display width and 75% of your display height. Which means that not
everyone gets the same default window. Something to consider when
writing turtle software for others.
You can set the window's size using the setup() method or function. You
can get the current window size using the window_width() and
window_height() methods or functions.
The screensize() method or function gets/sets the size of the backing
store for the window. Generally, the return value is of no use to you,
as the area the turtle can travel is the size of the window, so no
backing store needed. It's there for folks who, for example, want a
500x500 window onto a 2000x2000 plane that the turtle can wander. Then
scrollbars appear to allow you to move that peephole of a window about
the larger plane.
You can modify many of turtle's default behaviors with a turtle.cfg file.
You can also find this in the turtle documentation:
