Explanation / Answer

Answer::

>>> turtle.position()
(0.00,0.00)
>>> turtle.forward(25)
>>> turtle.position()
(25.00,0.00)
>>> turtle.forward(-75)
>>> turtle.position()
(-50.00,0.00)
>>> turtle.position()
(0.00,0.00)
>>> turtle.backward(30)

>>> turtle.position()
(-30.00,0.00)
>>> turtle.heading()
22.0
>>> turtle.right(45)
>>> turtle.heading()
337.0

>>> turtle.heading()
22.0
>>> turtle.left(45)
>>> turtle.heading()
67.0

>>> tp = turtle.pos()
>>> tp
(0.00,0.00)
>>> turtle.setpos(60,30)
>>> turtle.pos()
(60.00,30.00)
>>> turtle.setpos((20,80))
>>> turtle.pos()
(20.00,80.00)
>>> turtle.setpos(tp)
>>> turtle.pos()
(0.00,0.00)
