小编app*_*ver的帖子

我正在查看的网站有以下代码.

var d = new Date(1362236400000);

这个javascript日期对象以某种方式编码以下HTML输出,

"2/3/2013 10:00"

有人可以解释这个编码吗？我需要创建一个python脚本来操作这些javascript数字来重新创建HTML输出.谢谢!

我有一份清单清单.我想基于前三个元素获得所有唯一列表.如果有重复项,那么它应该只返回最后一项.所以例如基于此

[['one', 'two', 'three', 'teennn'], ['five', 'five', 'five', 'five'],
 ['seven', 'nine', 'ten', 'eleven'], ['one', 'two', 'three', 'four']]

我想要归还这个

[['five', 'five', 'five', 'five'],
 ['seven', 'nine', 'ten', 'eleven'], ['one', 'two', 'three', 'four']]

我有如下数据结构.

[{"league"=>:nba, "period"=>"h1","edge"=>-5.0, "home_team"=>"Cavaliers"},   
{"league"=>:nba, "period"=>"h1", "edge"=>-6.0, "home_team"=>"Pistons"}, 
{"league"=>:nba, "period"=>"h1", "edge"=>-6.0, "home_team"=>"Bucks"},   
{"league"=>:ncaab, "period"=>"h1", "edge"=>-7.0, "home_team"=>"Wisconsin"},   
{"league"=>:ncaab, "period"=>"h1", "edge"=>-7.0, "home_team"=>"Wisconsin"}]

我需要为数组中的每个元素分配一个新的键/值对,key = "id",value = x,其中x是一个整数.本x应是每一个元素,它同样"period"和"home_team"值是相同的,否则什么x是无所谓.所以上面应该会产生这样的结果:

[{"league"=>:nba, "period"=>"h1","edge"=>-5.0, "home_team"=>"Cavaliers", "id"=>1},   
{"league"=>:nba, "period"=>"h1", "edge"=>-6.0, "home_team"=>"Pistons", "id"=>2},    
{"league"=>:nba, "period"=>"h1", "edge"=>-6.0, "home_team"=>"Bucks", "id"=>3},  
{"league"=>:ncaab, "period"=>"h1", "edge"=>-7.0, "home_team"=>"Wisconsin", "id"=>4},   
{"league"=>:ncaab, "period"=>"h1", "edge"=>-7.0, "home_team"=>"Wisconsin", "id"=>4}]

我从一个简单的数组开始,如下:

a = ["a", "b", "c", "d", "e", "f"]

我想要下面的内容.我怎么得到这个？

a = ["ab", "cd", "ef"]
