Question

这是一个程序，需要3位数字，存储它们，并反复猜测和检查，直到三个存储的数字与3个猜测的数字相匹配。我似乎无法通过第一个while循环执行任何操作：

digitone = int(raw_input())
digittwo = int(raw_input())
digitthree = int(raw_input())
digitthree = int(raw_input())
countdigitone = 0
countdigittwo = 0
countdigitthree = 0

while digitone <= countdigitone:
    if digitone < countdigitone:
        print "Digit one could be", countdigitone
        countdigitone += 1
    elif digitone == countdigitone:
        print "Digit one is", countdigitone
        while digittwo <= countdigittwo:
            if digittwo < countdigittwo:
                print "The first two digits could be", countdigitone, countdigittwo
                countdigittwo += 1
            elif digittwo == countdigittwo:
                print "Digits one and two are", countdigitone, countdigittwo
                while digitthree <= countdigitthree:
                    if digitthree < countdigitthree:
                        print "The 3-digit number could be", countdigitone, countdigittwo, countdigitthree
                        countdigitthree += 1
                    elif digitthree == countdigitthree:
                        print "This is most definetly the number!", countdigitone, countdigittwo, countdigitthree
                        break

就是这样。目前，它只需要你的数字，打印单词none，然后停止。有什么方法可以解决这个问题吗？

Answer 1

while digitone <= countdigitone表示除非digitone是负数，否则它将永远不会小于设置为0的countdigitone

我会执行以下操作，循环直到找到每个数字的值并在结尾处打印值：

digit_one = int(raw_input())
digit_two = int(raw_input())
digit_three= int(raw_input())
count_digit_one = 0
count_digit_two = 0
count_digit_three= 0

while digit_one > count_digit_one:
    print "Digit one could be", count_digit_one
    count_digit_one += 1

while digit_two > count_digit_two:
    print "The first two digits could be", count_digit_one, count_digit_two
    count_digit_two += 1

while digit_three> count_digit_three:
    print "The first three digits could be", count_digit_one, count_digit_two
    count_digit_three += 1
print "This is most definitely the number! {}{}{}".format(count_digit_one, count_digit_two, count_digit_three)

Answer 2

第一个while循环正在执行

while digitone <= countdigitone:

您已从用户那里获得digitone。并且您已将countdigitone设置为0.除非他们输入的数字小于0，否则您根本不会进入while循环。

为什么这段代码不会执行？
