python基础学习笔记（二）2013-02-2416:25虫师阅读(...)评论(...)编辑收藏继续第一篇的内容，讲解，python的一些基本的东西。注释为了让别人能够更容易理解程序，使用注释是非常有效的，即使是自己回头再看旧代码也是一样。>>>#获得用户名：>>>user_name=raw_input("whatisyourname?")在python中用井号（#）表示注释。井号（#）右边的内存将不被程序执行。即使没有注释，也应该让代码本身易于理解。

分号不要在行尾加分号,也不要用分号将两条命令放在同一行.行长度每行不超过80个字符例外:长的导入模块语句注释里的URL不要使用反斜杠连接行.Python会将圆括号,中括号和花括号中的行隐式的连接起来,你可以利用这个特点.如果需要,你可以在表达式外围增加一对额外的圆括号.Yes:foo_bar(self,width,height,color='black',design=None,x='foo',emphasis=None,highlight=0)if(wi

背景最近在计划明年从北京rebase到深圳去，所以最近在看深圳的各个方面。去年在深圳呆过一段时间，印象最深的是，深圳总是突然就下雨，还下好大的雨。对于我这种从小在南方长大但是后面又在北京呆了2年多的人来说，熟悉而又无奈。今天早上本来想随便浏览浏览一个天气网站，看看深圳的历史天气如何的，但是，一不小心发现，这家网站竟然直接能用API来抓数据，这~~~还不抓一波，省的自己一个月一个月地看。先上最后的效果图：所有的code都在我的GitHub上：boydfd下面

本文实例形式讲解了Python3的条件与循环控制语句及其用法，是学习Python所必须掌握的重要知识点，现共享给大家供大家参考。具体如下：一般来说Python的流程控制语句包括：if条件语句、while循环语句、for循环语句、range函数以及break、continue、pass控制语句。这些语句在Python中的语义和在其他语言中基本是一样的，所以这里就只说它们的用法。一、if语句if语句是最常用的条件控制语句，Python中的一般形式为：if条件一

本文实例讲述了Python实现根据指定端口探测服务器/模块部署的方法，非常具有实用价值。分享给大家供大家参考借鉴。有些时候，在维护过程中，服务器数量非常多。应用模块部署在不同服务器上。有时维护人员做了模块迁移，而未及时同步至手册中。查找比较困难。于是，产生Python根据应用端口进行探测，获取模块部署。设想非常简单：通过简单的tcp链接，如果能够成功的建立，立即断开，防止影响业务。表示模块在某服务器上有部署。具体功能代码如下：#!/bin/envpytho
