Bonjour, 

mon programme utilise une classe qui a était importer avec la méthode import. La classe fait ses calcules est print le resultat. Comme reutiliser une variables de la classe dans le programme principal ? Comment extraire la valeur d'une variable se trouver sur une classe et par consequent sur un autre .py. Merci d'avance.

Qu'importe le fichier, tu peux accéder à la valeur de la classe en faisant objet.variable, à moins qu'il s'agisse d'une variable privée (commençant par __) mais du coup ce ne serait pas normal de vouloir y accéder.

Bonjour, j'ai le meme probleme mais objet.variable ne fonctionne pas ( AttributeError: 'module' object has no attribute 'data' ).

J'ai essayer var = eztxt.data,    je definis la variable data ligne 50 dans ma class.

Voici la class : 

# input lib

            else: exec('self.'+key[0]+' = '+key[1])
            assertions.append(key[0])
