python入门及IDE搭建

q528

IDE：eclipse3.8.2
插件：PyDev 2.8.2
python：python-2.7.6.amd64
具体软件，请朋友们自行下载。
版本一定要对应，pyDev只能选择2.8。选择3.4则eclipse3.8.2认不出来。另外快捷键会冲突，需要修改一下。
启动eclipse
【设置快捷键】
选择window -> preference -> General -> keys
查找Word completion，在binding:里面，按退格键（即：删除快捷键的意思）
查找Content Assist，在binding里面，添加快捷键alt+/

【关联python】
选择window -> preference -> PyDev -> INterpreters -> Python Interpreter
然后在上面的框里，new，设置python.exe的路径

【例子】
然后启动项目，快乐的体验python吧。其实入门很简单，找几个现成的例子学习一下就可以。
一个简单的demo，这个事我兄弟大伟写的，他的博客是http://ailikes.iteye.com/
其中的语法，都可以通过eclipse的自动提示进行完成。非常爽。基本语法包括异常处理，日期处理，文件操作，for循环，if语句等等吧。请大家自行体会吧
