turtle.Pen.tracer¶

Pen.tracer(flag=None, delay=None)¶

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
