python 好东东
ipython 如果没有用装, 那就赶紧装上, 这个东西比起python自己带的那个交互界面要好用很多
shutil 类似于shell的一些接口, 比如 cp, mv等等
subprocess 调用子进程
optparse 解析命令行参数的, 用它来应付命令行参数, 简洁, 清晰
sqlite3 数据库, 进程级的数据库, 很酷, 甚至可以把这个数据库建在内存里. http://www.python.org/doc/2.5.4/lib/module-sqlite3.html
urllib 处理url的, 对于一些简单的应用, 很好用

The Zen of Python, by Tim Peters
Beautiful is better than ugly.
Explicit is better than implicit.
Simple is better than complex.
Complex is better than complicated.
