这是一篇「抛砖」与「摆立场」的文章,欢迎有理有据的批判与讨论. 首先摆出个人的立场:「代码司法」,在一定程度上,是可以的,至少交互式断案是可行的.至于其「必要性」,则在于进一步去除司法过程中的「不公正」,并且赋予司法过程以「可重复性」. 1 首先举一个实际的例子,下图是1998年袭击东非大使馆的人员网络: 1998年袭击东非大使馆的人员网络 我们要找到他们的合作关系,也就是找出他们中有几个团体,这是可以通过代码做到的: clique = FindClique[g, {5}, All] {{&Fa

在公司里做的一个接口系统,主要是对接第三方的系统接口,所以,这个系统里会和很多其他公司的项目交互.随之而来一个很蛋疼的问题,这么多公司的接口,不同公司接口的稳定性差别很大,访问量大的时候,有的不怎么行的接口就各种出错了. 这个接口系统刚刚开发不久,整个系统中,处于比较边缘的位置,不像其他项目,有日志库,还有短信告警,一旦出问题,很多情况下都是用户反馈回来,所以,我的想法是,拿起python,为这个项目写一个监控.如果在调用某个第三方接口的过程中,大量出错了,说明这个接口有有问题了,就可以更快的采
问:现在已经可以用javascript(nodejs)写服务端的代码,但如果是为了语言一致性的话,为什么没人去做过python在浏览器端的实现呢? 答:这个问题其实与Python没半毛钱关系,比如可以把最后一句改成为什么没人去做ruby在浏览器端的实现呢?还可以改成为什么没人去做java在浏览器端的实现呢?等等. 从历史的角度来看,JavaScript的发展一直与浏览器密不可分,最初由网景公司的Brendan Eich设计,叫LiveScript,后与Sun公司合作,改为JavaScript.后

以下做法与你将读到的内容完全背离,那就是为你的表单点缀漂亮的按钮,颜色以及排版甚至充沛的jQuery插件,这些都无助于可用性.事实上,这么做你只是(通过没有归整过的方式)实现了表单可用性的三分之一. 在这篇文章中,我们将提供便于你执行且切实可行的规范.这些精心编排制作的规范是来源于可用性测试,实施现场测试,网络站点追踪,视线追踪,网页在线分析及客户支持部门获取的客户投诉. 为什么网络表单可用性如此重要 ISO 9241标准将网站可用性定义为&高效,有效地满足特定用户在某个环境中达到特定目的.&q
这篇文章主要是对我收集的一些文章的摘要.因为已经有很多比我有才华的人写出了大量关于如何成为优秀Python程序员的好文章. 我的总结主要集中在四个基本题目上:函数式编程,性能,测试,编码规范.如果一个程序员能将这四个方面的内容知识都吸收消化,那他/她不管怎样都会有巨大的收获. 函数式编程 命令式的编程风格已经成为事实上的标准.命令式编程的程序是由一些描述状态转变的语句组成.虽然有时候这种编程方式十分的有效,但有时也不尽如此(比如复杂性) -- 而且,相对于声明式编程方式,它可能会显得不是很直观.

7 &&& type(input_B)
8 &type ‘int‘&
例子 1 可以看到：这两个函数均能接收 字符串 ，但 raw_input() 直接读取控制台的输入（任何类型的输入它都可以接收）。而对于 input() ，它希望能够读取一个合法的 python 表达式，即你输入字符串的时候必须使用引号将它括起来，否则它会引发一个 SyntaxError 。
例子 2 可以看到：raw_input() 将所有输入作为字符串看待，返回字符串类型。而 input() 在对待纯数字输入时具有自己的特性，它返回所输入的数字的类型（ int, float ）；同时在例子 1 知道，input() 可接受合法的 python 表达式，举例：input( 1 + 3 ) 会返回 int 型的 4 。
就是说input处理数字的时候会确定类型，而raw_input全都是字符型，无所谓。
