I am writing an address book. The function below should change the address and then terminate the while loop. But why doesn't the break statement work?

Question

Python

def change():
    while True:
        ch = input('\tВведите имя контакта чей адресс вы хотите изменить:\n')
        if ch == '':
            print('вы ничего не ввели')

        for c, v in ab.items():
            if c == ch:
                new_address = input('Введите новый адресс:\n')
                ab[c] = new_address
                print('Адресс успешно изменен')
                break

Answer 1

Because break breaks the first loop it's in, which is for. In this case, get a boolean variable and execute while for example when it is true, and together with break change its value to false
