Question

每当我运行我的程序时，随机打印数字10，我不知道它的来源。有人帮帮我吗？

＆＃13;

def main():
    phoneNumber=int(input("Enter a 10 digit unformatted telephone number in the format ##########: "))
    tempNumber = []
    phoneNumber = str(phoneNumber)
    length = len(phoneNumber)
    index=0
    print(length)


    if (length ==10):
        print("The unformatted number is: ",phoneNumber)
    else:
        print("The telephone number was NOT entered in unformatted format ##########.")

    for num in phoneNumber: 
        tempNumber.append(num)

    tempNumber.insert(0,"(")
    tempNumber.insert(4,")")
    tempNumber.insert(8,"-")
    phoneNumber = ''.join(tempNumber)
    print("The formatted number is: ",phoneNumber)

main()

＆＃13;

Answer 1

您正在打印用户给出的输入长度，以便打印10的原因（请参阅main（）函数中的语句编号6）。

phoneNumber = str(phoneNumber)
length = len(phoneNumber)
index = 0
print(length)  # <--- this statement is printing the length of the input
