python 2.7 的 While 和 Break 语句

Question

我是 python 的新手，所以我想知道是否有人可以帮我弄清楚我的 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。

我研究了这个主题，发现我找到的所有示例都倾向于数字等，或者所提供的信息对我来说并不合适。

因此，我们将不胜感激。

虽然正确：

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

中断如果应该是：

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":
