Bonjour à tous,

Je suis débutant en Python et cherche à proposer à mes élèves de 4° un exercice sur le théorème de Pythagore.
J'arrive à obtenir de nouveaux énoncés dans la même fenêtre mais, les solutions ne correspondent pas aux énoncés.
Voici le code de l'exercice :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

fenetre.mainloop()

Si j'enlève, dans la réponse,
a = random.randint(1,20)
c = random.randint(1,20)
j'obtiens toujours la même solution, quel que soit l'énoncé.

Je vous remercie pour votre aide, même partielle.
