SPOJ模式给出运行时错误Python

问题描述如下：

过程：将两个列表作为输入，使用Python中的sort方法对它们进行排序，然后打印总和

代码：

import sys,os
#Need to maximize the product of two lists 
def process(index,line):
    p=line.split(" ")
    #print 'Line after splitting',p
    for i in p:
        if(index==0):
            men.append(int(i))
        else:
            women.append(int(i))

global men
global women
men=[]
women=[]    
''' First, you enter number of times you want to compare . 
    Second, you enter number of men/women 
    Then, you enter the real data 
'''


n=int(raw_input()) #This is for number of shows
num = int(raw_input()) #This is number of men/women


for t in range(0,n): #Do this "n" times

    men = []
    women = []
    for i in range(0,2): #Now, enter  the men data first  and women next

        line=raw_input()
        process(i,line)
    p=0

    temp = []
    men.sort()
    women.sort()

    for i in range(0,num):
        p = p + men[i]  * women[i]
    print p

问题：它不断给出运行时错误：

我处理过的一些案例：

In [16]: %run /home/crazyabtliv/SPOJ/Fashion.py
2
3
1 1 1
2 3 4
9
4 5 6
0 9 8
94

In [14]: %run /home/crazyabtliv/SPOJ/Fashion.py
1
5
1 1 0 0 0
10 10 9 9 9
20

谢谢

这就是SPOJ所期望的：

Input:
2
2
1 1
3 2
3
2 3 2
1 3 2

Output:
5
15

但是，尝试运行程序会产生以下结果：

2
2
1 1
3 2
5      <- that is the output for the first contest. should not output yet
3
2 3 2
Traceback (most recent call last):
  File "dasdsad.py", line 35, in <module>
    p = p + men[i]  * women[i]
IndexError: list index out of range

C:\Python26\programas\zz_so>

但代码仍然可以大大简化：

def process(line):
    return sorted([int(i) for i in line.split()])

n = int(raw_input())         #This is for number of shows
results = []
for t in range(n):           #Do this "n" times
    num = int(raw_input())   #This is number of men/women

    men = process(raw_input())
    women = process(raw_input())

    p = sum(m*w for m, w in zip(men, women))
    results.append(p)

for item in results:
    print item

编辑：我用sumgenerator_expression而不是for循环对代码进行了一些优化

您的代码是什么？为什么不尝试用。您得到相同的输出吗？谢谢！这两件事。修改后的代码教会了我很多：下一次会写得更好！再次感谢不客气。如果关注代码，您可以做更多的事情。例如，你可以用p=sum[m*w代表m，w代表zipmen，women]@crazyaboutliv改变'p=0代表rangenum中的i:p=p+men[i]*women[i]`最后一件事：如果你正在编写spoj代码，并且想用其他人的意见分析和改进你的运行代码，你可能想发布你的建议以表示感谢！非常感谢！我们将从现在开始这样做。现在与主发电机战斗：可以吗soon@crazyaboutliv行动！错了，似乎是斯波吉人。嗯，我承认他们是对的。

def process(line):
    return sorted([int(i) for i in line.split()])

n = int(raw_input())         #This is for number of shows
results = []
for t in range(n):           #Do this "n" times
    num = int(raw_input())   #This is number of men/women

    men = process(raw_input())
    women = process(raw_input())

    p = sum(m*w for m, w in zip(men, women))
    results.append(p)

for item in results:
    print item
