(self, flag=None, delay=None)
return self.screen.tracer(flag, delay)
Turns turtle animation on/off and set delay for update drawings.

        Optional arguments:
        n -- nonnegative  integer
        delay -- nonnegative  integer

        If n is given, only each n-th regular screen update is really performed.
        (Can be used to accelerate the drawing of complex graphics.)
        Second arguments sets delay value (see RawTurtle.delay())

        Example (for a Turtle instance named turtle):
        >>> turtle.tracer(8, 25)
        >>> dist = 2
        >>> for i in range(200):
        ...     turtle.fd(dist)
        ...     turtle.rt(90)
        ...     dist += 2
