il montre "ligne 42, dans si input_! = 'no': NameError: le nom 'input_' n'est pas défini" quand je donne non en première ligne. Comment puis-je le corriger?

La variable input_ est initialisée à l'intérieur de la fonction rock_paper_scissors () ce qui signifie qu'en dehors de celle-ci (la portée de la fonction) n'est pas définie. Nous devons donc le mettre dans une fonction ou rendre input_ global.

def rock_paper_scissors():
    comp_score = your_score = 0
    y, z = "This is a rock paper scissors game. ", "Do you wish to play"
    x= ["rock", "paper", "scissors"]
    input_=input(y + z + "?")
    if input_ == "no":
       return
    else: # no need for: if input_ != "no"
       a = input("Do you wanna play again?")
rock_paper_scissors()

J'espère que cela vous aidera.

Voici mon point de vue, il reste encore du travail, il est fonctionnel ...
