turtle.ondrag()

turtle.ondrag(fun, btn=1, add=None)

Parameters:	fun – a function with two arguments which will be called with the coordinates of the clicked point on the canvas num – number of the mouse-button, defaults to 1 (left mouse button) add – `True` or `False` – if `True`, a new binding will be added, otherwise it will replace a former binding

Bind fun to mouse-move events on this turtle. If fun is None, existing bindings are removed.

Remark: Every sequence of mouse-move-events on a turtle is preceded by a mouse-click event on that turtle.

>>> turtle.ondrag(turtle.goto)

Subsequently, clicking and dragging the Turtle will move it across the screen thereby producing handdrawings (if pen is down).
