python 2.7的while和break语句

Question

我对 python 比较陌生，所以我想知道是否有人可以帮助我找出我的 while 循环和 break 语句。

我可以让它继续或中断，但不能两者兼而有之。

我对该主题进行了研究，发现我发现的所有示例都倾向于数字等，或者提供的信息对我来说并不适用。

因此，我们将不胜感激。

该计划旨在计算您的每周工资。

当真时：

Hours_Worked = int(raw_input("How many hours have you worked this week?:\n"))#This line of code allows the user to input the amount of hours they have worked in whole numbers only.


Hourly_Rate = float(raw_input("What is your hourly rate?:\n" u"\u00A3"))#This line of code allows the user to input their hourly rate of pay in floating numbers to wither a whole or decimal points.


Tax = int(raw_input("What is your current Tax rate?:\n" u"\u0025"))#This line of code allows the user to input their tax rate.


Nat = int(raw_input("What is your National Insurance rate?:\n" u"\u0025"))#This line of code allows the user to input their National Insurance rate.


Total_Weekly_Pay = (Hours_Worked*Hourly_Rate)#This line of code works out the weekly pay before deductions.


Total_Weekly_Pay_After_Deductions = Total_Weekly_Pay - (Tax*Total_Weekly_Pay/100) - (Nat*Total_Weekly_Pay/100)# This line of code works out the weekly pay after deductions. The Tax and National Insurance rate are worked out by multiplying and then dividing.


print "Your Total weekly pay before deductions is\n" u"\u00A3%5.2f" %(Total_Weekly_Pay)#This line of code prints out the weekly pay before deductions to the floating points of 5.2.


print "Your Total weekly pay after Tax and National Insurance deductions is\n" u"\u00A3%5.2f" %(Total_Weekly_Pay_After_Deductions)#This line of code prints out the weekly pay after deductions to the floating points of 5.2.

cont = raw_input("Would you like to try again? (yes/no)\n")
if cont == "no":
    print "Goodbye"
    break

Answer 1

打破如果应该是：

if cont == "":

或者你告诉用户退出的值，所以：

cont = raw_input("Would you like to try again?  (Yes/No")
if cont == "No":
