turtle.shapesize()

turtle.shapesize(stretch_wid=None, stretch_len=None, outline=None) turtle.turtlesize(stretch_wid=None, stretch_len=None, outline=None)

Return or set the pen’s attributes x/y-stretchfactors and/or outline. Set resizemode to “user”. If and only if resizemode is set to “user”, the turtle will be displayed stretched according to its stretchfactors: stretch_wid is stretchfactor perpendicular to its orientation, stretch_len is stretchfactor in direction of its orientation, outline determines the width of the shapes’s outline.
