2 значения выводятся

у меня в коде почемуто выводится 2 значения помогите плиз

def replbank():

    ISSUER_ID = {
        'VISA' : 461259,
        'VISA1' : 488984,
        'VISA2' : 404267,
        'VISA3' : 457802
    }

    


    def issuerId(key: str = 'VISA') -> int:
        return ISSUER_ID.get(key)
    def issuerId1(key: str = 'VISA1') -> int:
        return ISSUER_ID.get(key)
    def issuerId2(key: str = 'VISA2') -> int:
        return ISSUER_ID.get(key)
    def issuerId3(key: str = 'VISA3') -> int:
        return ISSUER_ID.get(key)

    operators = [issuerId(), issuerId1(), issuerId2(), issuerId3()]

    choice = random.choice(operators)
    def checkLuhn(list_int: list) -> bool:
        c_sum = list_int[-1]
        tmp_v = {i: v * 2 for i, v in enumerate(list_int[:-1]) if i == 0 or i % 2 == 0}
        for k, v in tmp_v.items():
            if v >= 10:
                y = str(v)[0]
                z = str(v)[1]
                w = int(y) + int(z)
                tmp_v.update({k: w})
        for k_, v_ in tmp_v.items():
            list_int[k_] = v_
        res = sum(list_int[:-1]) * 9
        if str(res)[-1] == str(c_sum):
            return True
    def userId() -> int:
        return randint(1111111111, 9999999999)

    iid = str(choice)
    uid = str(userId())
    num = iid + uid
    l_tmp = [int(i) for i in num]
    while not checkLuhn(l_tmp):
        num = str(choice) + str(userId())
        l_tmp = [int(i) for i in num]
    return num
print(replbank())

Почемуто выводятся два значения Пример:
