Python IF 查询

我正在尝试制作一个计算入场费的程序。我已经设法做到了，除了一个部分，如果有两个成人和三个 child ，那么费用是 15 美元。这应该使用 if 语句来完成吗？我该怎么做？

import math  
 
loop = 1 
choice = 0 
while loop == 1: 
 
    print "Welcome" 
 
    print "What would you like to do?:" 
    print " " 
    print "1) Calculate entrance cost" 
 
    print "2) Leave swimming centre" 
    print " " 
 
    choice = int(raw_input("Choose your option: ").strip()) 
    if choice == 1: 
        add1 = input("Adults: ") 
        add2 = input("Concessions: ") 
        add3 = input("Children: ") 
        print add1, "+", add2, "+", add3, "answer=", add1 *5 + add2 *3 + add3 *2    
    elif choice == 2: 
        loop = 0 

提前感谢您的任何帮助，我们将不胜感激!!

请您参考如下方法:

您应该为特殊情况放置一个 if 语句，其中有 2 名成人和 3 名 child 。否则你应该正常计算它。我已经评论了发生这种特殊情况的区域。

此代码还假定特殊情况不会影响优惠价格。

import math  
 
loop = 1 
choice = 0 
while loop == 1: 
 
    print "Welcome" 
 
    print "What would you like to do?:" 
    print " " 
    print "1) Calculate entrance cost" 
 
    print "2) Leave swimming centre" 
    print " " 
 
    choice = int(raw_input("Choose your option: ").strip()) 
 
    if choice == 1: 
        add1 = input("Adults: ") 
        add2 = input("Concessions: ") 
        add3 = input("Children: ") 
 
        cost = 0 
 
        # special case for 2 adults, 3 children 
        if add1 == 2 and add3 == 3: 
            cost += 15 
        else: 
            cost += add1*5 + add3*2 
 
        # concession cost 
        cost += add2 *3 
 
        print add1, "+", add2, "+", add3, "answer=", cost 
 
    elif choice == 2: 
        loop = 0
