将python文件保存在python  安装文件夹的tmp文件夹中,
如: e:"Python25"tmp中,右击该文件,选择Edit with Idle选项,
在 Python Shell-> File-> Open 打开文件,弹出一个新的窗口,
选择 Run-> Run Module,会运行并得出结果.

Windows 的文件类型关联
如无法打开RUBY文件时:

> assoc .rb
File association not found for extension .rb

如果没有关联,则给它一个相关的文件类型:
> assoc .rb=rbFile

接着测试文件类型是否存在:
> ftype rbFile
File type 'rbFile' not found or no open command associated with it.

如果不存在,则手动建立:
> ftype rbFile="E:"Program Files"Windows NT"Accessories"wordpad.exe" "%1" %*
wordpad.exe(写字板)的路径自己定的.

最后,把 .rb加入环境变量PATHEXT中。如：
PATHEXT=.COM; .EXE; .BAT; .WSH; .rb
