无法循环到输入验证代码中的某个点答案

【问题标题】：Trouble looping to a point in input validation code无法循环到输入验证代码中的某个点
【发布时间】：2021-11-23 02:30:07
【问题描述】：

我无法弄清楚如何将我的代码循环回特定点，我有 2 个循环点，第一个工作正常，但我无法让第二个工作，因为我必须定义整数变量“num_stores_int”，但如果我这样做，那么“while”循环将不起作用。请参阅我的代码以了解这些点的位置。

这是我的代码：

num_stores = ("")
num_stores_int = int(num_stores)
while num_stores.isnumeric() == False:
    while num_stores_int > 10: #This is where I want it to loop to 
        num_stores = input ("\n To start, please enter the amount of stores you own: ")
        if num_stores.isnumeric() == True:
            num_stores_int = int(num_stores)
            if num_stores_int > 10: #this is where I want the "while" loop to validate the integer being less than 10
                print (" Sorry, this sales tracker can track a maximum of 10 stores.\n Here, try that again, I'll reboot it for you.\n")
                print (" -----------------------REBOOTING------------------------")
            if num_stores_int >= 5:
                print ("\n Hmm, interesting, you'd think someone with that many \n stores would be able to afford a better sales tracker.")
                print (" Well, I guess you're stuck with me! MUHAHAHAHA!!......\n\n Anyway,")
                print (f" clearly big business person, you own {num_stores_int} stores.\n I'm gonna need you to tell me where each one is")
            else:
                num_stores_int = int(num_stores)
                print (f" Alright... so, random business person, you have {num_stores_int} stores.\n Now, I'm going to need you to tell me where each one is")
        else:
            print ("\n Hey, uhh, you're going to have to write a number for the\n amount of stores you've got, letters and decimals don't \n really work. Here, try again, I'll reboot it for you.\n")
            print (" -----------------------REBOOTING------------------------")

将if num_stores_int >= 5: 更改为elif num_stores_int >= 5:

不清楚您在寻找什么，但我相信您的外部 while 循环是为了在用户输入非数字内容时不断询问用户输入？

我只会将 while 循环包裹在要求用户输入的代码周围，如下所示：

num_stores = ("")
num_stores_int = 0
while num_stores_int < 10: #This is where I want it to loop to
    num_stores = input ("\n To start, please enter the amount of stores you own:")
    while num_stores.isnumeric() == False:
        print ("\n Hey, uhh, you're going to have to write a number for the\n amount of stores you've got, letters and decimals don't \n really work. Here, try again, I'll reboot it for you.\n")
        print (" -----------------------REBOOTING------------------------")
        num_stores = input ("\n To start, please enter the amount of stores you own:")

    num_stores_int = int(num_stores)
    if num_stores_int > 10: #this is where I want the "while" loop to validate the integer being less than 10
        print (" Sorry, this sales tracker can track a maximum of 10 stores.\n Here, try that again, I'll reboot it for you.\n")
        print (" -----------------------REBOOTING------------------------")
    elif num_stores_int >= 5:
        print ("\n Hmm, interesting, you'd think someone with that many \n stores would be able to afford a better sales tracker.")
        print (" Well, I guess you're stuck with me! MUHAHAHAHA!!......\n\n Anyway,")
        print (f" clearly big business person, you own {num_stores_int} stores.\n I'm gonna need you to tell me where each one is")
    else:
        print (f" Alright... so, random business person, you have {num_stores_int} stores.\n Now, I'm going to need you to tell me where each one is")

是的，外部 while 循环对我有用，但内部循环不是，因为我必须定义整数变量 num_stores_int 以检查它是否在数字 10 以下，但如果我这样做了，它'将采用已经定义的值，而不是用户输入的值，因此不起作用
@Clandestinity 你能否更具体地说明我发布的代码中哪些内容不起作用
哎呀，我没注意到变化，还以为你只是重新发布了我的相同代码。哇，我没想到它会起作用。非常感谢你！
@Clandestinity 我看到你是新来的。如果您认为某个答案解决了问题，请单击绿色复选标记将其标记为“已接受”。这有助于将注意力集中在仍然没有答案的旧 SO。
很明显的 xD，谢谢，我一直在寻找将其标记为正确答案的东西。对不起，时间不早了，我的脑子都炸了XD

【解决方案2】：

我的错，我一定没有很好地解释出了什么问题，但我只是尝试了一些东西，它奏效了。

def restart():
    num_stores = ("")
    while num_stores.isnumeric() == False: 
        num_stores = input ("\n To start, please enter the amount of stores you own: ")
        if num_stores.isnumeric() == True:
            num_stores_int = int(num_stores)
            if num_stores_int > 10:
                print ("\n Sorry, this sales tracker can track a maximum of 10 stores.\n Here, try that again, I'll reboot it for you.\n")
                print (" -----------------------REBOOTING------------------------")
                restart()
            elif num_stores_int >= 5:
                print ("\n Hmm, interesting, you'd think someone with that many \n stores would be able to afford a better sales tracker.")
                print (" Well, I guess you're stuck with me! MUHAHAHAHA!!......\n\n Anyway,")
                print (f" clearly big business person, you own {num_stores_int} stores. I'm gonna\n need you to tell me where each one is")
            else:
                num_stores_int = int(num_stores)
                print (f" Alright... so, random business person, you have {num_stores_int} stores.\n Now, I'm going to need you to tell me where each one is")
        else:
            print ("\n Hey, uhh, you're going to have to write a number for the\n amount of stores you've got, letters and decimals don't \n really work. Here, try again, I'll reboot it for you.\n")
            print (" -----------------------REBOOTING------------------------")
restart()
