Méthode turtle.TurtleScreen.onkeyrelease

Signature de la méthode onkeyrelease

def onkeyrelease(self, fun, key) 

Description

help(TurtleScreen.onkeyrelease)

Bind fun to key-release event of key.

        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):

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

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