Help! Nu pot opri o functie din a rula la nesfarsit(Python)

Recommended Posts

Salut! Am un mic blocaj in demersul meu de a invata python. Fiind vorba de functii (banale pentru unii) am in poza atasata o poza a ecranului. Cand incerc sa tastez 'a' de exemplu,  merge la nesfarsit; cum as putea sa opresc asta si sa afiseze doar o data? am incercat eu cate ceva dar ori mi-a dat eroare, ori mergea la fel. 

Asta e poza: https://ibb.co/SXfqFB7

P.S. : ignorati textul; e un fel de inside joke :))

In functia menu() tu iei inputul de la user in user_input dupa care te bagi direct in while loop.

Valoarea user_input nu se poate schimba niciodata pt ca tu esti blocat in while:

 

def menu():
    user_input='fara valoare' # intrii in loop cu o valoare default
    
    while user_input != 'q':
        user_input = input("*inside joke*: ") # inputul in citesti in interiorul loopului
        if user_input == 'a':                # cand while se executa a 2-a oara promptul de input se executa din nou
            print("ai tastat a")
        elif user_input == 'b':
            print("ai tastat b")
        else:
            print("nu stii sa tastezi?")
    #nu mai are rost aici sa mai citesti input

Sper sa intelegi tu cum functioneaza while-ul. Daca inca nu te prinzi incearca un step-by-step debugging. (http://pythontutor.com/)
