我建议你完成工作 http://www.amk.ca/python/howto/regex/
通过工作，我不会意思是读。我的意思是每个新概念引入
：
1.在交互式提示下自己尝试给出的示例
2.尝试示例的变化
3.阅读图书馆参考手册的相关部分
我也建议在这个新闻组中阅读线程，其中人们是
向re求助。
HTH，
John
I suggest that you work through the re HOWTO
http://www.amk.ca/python/howto/regex/
and by work through, I don''t mean "read". I mean as each new concept
is introduced:
1. try the given example(s) yourself at the interactive prompt
2. try variations on the examples
3. read the relevant part of the Library Reference Manual
Also I''d suggest reading threads in this newsgroup where people are
asking for help with re.
HTH,
John
