while和break語句python 2.7

Question

我對Python很陌生，所以我想知道是否有人可以幫我弄清我的while循環和break語句。

我可以讓它繼續或中斷，但從來都沒有。

我研究了這個主題，發現我發現的所有例子都傾向於數字等，或者提供的信息只是不點擊我。

所以，任何幫助，將不勝感激。

此計劃旨在計算您的每週工資。

而真：

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，如果應該是：

if cont == "": 

或數值告訴出境的用戶，所以：

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