Signature de la méthode tracer

def tracer(self, n=None, delay=None) 

Description

help(TurtleScreen.tracer)

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 TurtleScreen instance named screen):
        >>> screen.tracer(8, 25)
        >>> dist = 2
        >>> for i in range(200):
        ...     fd(dist)
        ...     rt(90)
        ...     dist += 2
