为什么80%的码农都做不了架构师？>>> 
http://dlwt.csdn.net/fd.php?i=858467711513251&s=27caceefbe77d6532f648bb5ae3bc048 这个是Python for MyEclipse的插件
http://dlsw.baidu.com/sw-search-sp/soft/6e/17016/python-3.3.5.1418106245.msi 这个是Python for Windows 安装文件
安装好所需要的文件 。即可在MyEclipse里面开始Python最简单的测试了。
首先选择Python的编译器 在MyEclipse Windows-preferences New
输入名称
选择编译器
选择所有的 确认OK 等待一下安装
完毕之后 就可以开始创建Python工程测试了
选择project
选择Pydev Project 下一步
选择个语法版本2.5
对工程src -NEW -PyDev Module
新建的后缀名为 .py 自动会切换到PyDev perspective 这个视图下可以更好的编辑。
hello world 代码就一行 比java的少了很多。
简单的安装和Python代码运行测试就是这样。很简单。都不需要duang duang duang的。
简单的基础运用代码 可以自己试试一下哦。
