    404 <p>
    405 Vous disposez des fonctions
    406 <code>droite()</code>,
    407 <code>gauche()</code>,
    408 <code>haut()</code>, et
    409 <code>bas()</code>
    410 pour faire avancer le robot.
    411 </p>
    412 
    413 <p>
    414 Maintenant vous devez définir vous-même la fonction
    415 <code>z()</code>
    416 avant de l'appeler.
    417 </p>
    418 
    419 <p>
    420 Exemple de définition et d'appel de fonction :
    421 <pre><code># on définis la fonction f :
    422 def f():
    423    # elle contient le code suivant :
    424    print("Bonjour !")
    425 
    426 # on appelle la fonction f :
    427 f()
