Fonction onkeypress - module turtle

Signature de la fonction onkeypress

def onkeypress(fun, key=None) 

Description

help(turtle.onkeypress)

Bind fun to key-press event of key if key is given,
        or to any key-press-event if no key is given.

        Arguments:
        fun -- a function with no arguments
        key -- a string: key (e.g. "a") or key-symbol (e.g. "space")

        In order to be able to register key-events, TurtleScreen
        must have focus. (See method listen.)

        Example (for a TurtleScreen instance named screen
        and a Turtle instance named turtle):

        >>> def f():
        ...     fd(50)
        ...     lt(60)
        ...
        >>> onkeypress(f, "Up")
        >>> listen()

        Subsequently the turtle can be moved by repeatedly pressing
        the up-arrow key, or by keeping pressed the up-arrow key.
        consequently drawing a hexagon.
