]]>1146-python 复杂排序简单应用http://www.cppblog.com/panzhizhou/articles/206998.htmlpzzpzzSat, 17 May 2014 07:00:00 GMThttp://www.cppblog.com/panzhizhou/articles/206998.htmlhttp://www.cppblog.com/panzhizhou/comments/206998.htmlhttp://www.cppblog.com/panzhizhou/articles/206998.html#Feedback0http://www.cppblog.com/panzhizhou/comments/commentRss/206998.htmlhttp://www.cppblog.com/panzhizhou/services/trackbacks/206998.htmlstruct node{
string name,
int year,
int month,
int day,
};
通常我们需要自定义写我们的cmp函数，但是我发现在pyhon当中，from operator import itemgetter, attrgetter 这两个东西来做排序而很方便，如下：

res=sorted(res,key=itemgetter(1,2,3))
这样我们发现，就先按year，month，day这样的顺序做好排序了。
这一题的python代码如下： 1 import os

2 from operator import itemgetter, attrgetter
3
4 N=int(raw_input())
5 res=[]
6 for i in range(N):
7     in_s=raw_input()
8     li=in_s.split()  #default split with blank
9     res.append(tuple(li))
10
11 #sorted(students, key=itemgetter(1,2))
12
13 res=sorted(res,key=itemgetter(1,2,3))
14
15 for i in range(N):
16     print res[i][0]
17
18
