我應該如何添加/重做這個python腳本來輸入一個值並打印出所有的？

Question

我需要爲每個座位輸入一個值，並在用戶輸入'q'退出時讓腳本輸出所有座位的總數。這裏是到目前爲止的代碼：

cost = [] 
print 'Welcome to the receipt program!' 
while True: 
    cost = raw_input("Enter the value for the seat ['q' to quit]: ") 
    if cost == 'q': 
     break 
print '*****' 
print 'Total: $', cost 

Answer 1

totalCost = 0 
print 'Welcome to the receipt program!' 
while True: 
    cost = raw_input("Enter the value for the seat ['q' to quit]: ") 
    if cost == 'q': 
     break 
    else: 
     totalCost += int(cost) 

print '*****' 
print 'Total: $', totalCost
