turtle.speed()¶

turtle.speed(speed=None)¶

Return or set the turtle’s speed.

Optional argument: speed – an integer in the range 0..10 or a speedstring (see below)

Set the turtle’s speed to an integer value in the range 0 .. 10. If no argument is given: return current speed.

If input is a number greater than 10 or smaller than 0.5, speed is set to 0. Speedstrings are mapped to speedvalues in the following way:

‘fastest’ : 0 ‘fast’ : 10 ‘normal’ : 6 ‘slow’ : 3 ‘slowest’ : 1

speeds from 1 to 10 enforce increasingly faster animation of line drawing and turtle turning.

Attention: speed = 0 : no animation takes place. forward/back makes turtle jump and likewise left/right make the turtle turn instantly.

Example: >>> speed(3)
