'Return the TurtleScreen object, the turtle is drawing  on.
No argument.
Return the TurtleScreen object, the turtle is drawing  on.
So TurtleScreen-methods can be called for that object.
Example (for a Turtle instance named turtle):
>>> ts = turtle.getscreen()
>>> ts
<turtle.TurtleScreen object at 0x0106B770>
>>> ts.bgcolor("pink")'

def getscreen(self):

    return self.screen
