NameError:未定义名称“TotalCostRS”

Question

最近，我一直在开发一个代码，允许用户根据婚姻状况和是否有孩子来制定保险计划，并将总数相加。唯一的问题是，当我想要得到总数时，输出内容如下：

NameError: name 'TotalCostRS' is not defined

此错误也适用于输入的任何其他选项，仅“TotalCost”变量切换到未定义的变量之一

我的代码：

import random
from random import randint
ReferenceID = int(random.randint(1000,9999))
ReferenceIDInstances = 0
FamilyStatus = False
LSCounter = int(1)
RSCounter = int(1)

LFCounter = int(1)
RFCounter = int(1)
HFCounter = int(1)
LFCCounter = int(1)
RFCCounter = int(1)
HFCCounter = int(1)
while ReferenceID >= 10000 or ReferenceIDInstances!= 1:
ReferenceIDInstances += 1
print("This inquiry reference ID is:", ReferenceID)
print("If you are an administrator, enter ADMIN to view all inquiries.")
UserID = int(input("Please enter your four digit PIN:" + "\n"))
if(UserID <= 1000 or UserID >= 100000):
print("User ID is invalid. Please try again.")
else:
    Continue = "Y"

    TC9 = TotalCostHFC*HFCCounter        
    sum(TC1,TC2,TC3,TC4,TC5,TC6,TC7,TC8,TC9)

This is the sample expected output that we have been told to recreate:

Please enter the client’s ID or ’0’ to quit: 5555
Please enter the plan level as L, R or H (Low, Regular or High):h
Please enter the type of coverage (S for single and F for family): f
Please enter status as C or NC for (children or no children): nc
ID: 5555Payment: $99.45
Please enter the client’s ID or ’0’ to quit: 0
Total payment is $440.6 

我将非常感谢在解决此问题方面能得到的任何帮助。

TotalCost*变量的定义在if块中。如果这些块不运行（条件不满足），那么这些变量将不会被定义。但是您有一个无条件的代码块，您希望在其中定义所有这些TotalCost*变量。因此出现了错误。要修复，请无条件地定义这些变量&；将它们初始化为一些合理的默认值
