Bonsoir,

Je me demandais, est-ce qu'il est possible, si un module ne contient qu'une seule classe, de connaitre le nom de cette classe ?

Exemple:

plugin = __import__(name)
classe = plugin.MyClass()

Là je suis obligé d'appeler ma classe MyClass, mais si je voulais lui donner un nom plus explicite, et récupérer ce nom depuis un autre module, de manière générique, comment je pourrais faire ?

Bien à vous.

>>> module = __import__('sys')
>>> 'argv' in module.__dict__
True

Non ?

Quand tu importes un module, tu peux utiliser son attribut __dict__ (ou la méthode getattr) pour retrouver tous les objets (classes, fonctions, ...) que tu as importés.

Oui, ça je le sais, c'est donc bien pour ça que je me demande à quoi ça sert.

Ça, c'est le dictionnaire en question. Comme tu le vois, on voit bien l'objet MyClass, mais impossible de le différencier des autres. Donc ça ne répond pas vraiment à la question.
