我是真的没分了 请帮帮忙 。。。
在PYTHON 2.1 宝典 上的一个例子 可是我不知道如何运行它
请问是用IDLE 运行吗 ？ 麻烦写个运行过程

------解决方案--------------------
这个程序需要接受运行参数的，你需要启动一个cmd窗口：
开始菜单-> 运行-> cmd
从窗口中进入你的代码所在目录，比如你把代码保存为D:\projects\python\main.py
那么在cmd窗口中依次键入：
D:
cd projects
cd python
然后运行你的脚本:
python main.py 其他参数
这个“其它参数”需要参考你用的书。书上应该讲清除了怎样使用这个脚本。
