你好 Xianming,
I have a book -- *Python 核 心 编 程 (第二版)* -- that is for people who already
program but want to learn Python. It is available in China from at least 3
online stores:

tooting my own horn, http://corepython.com gets good reviews too. however,
it does target existing programmers who want to learn Python as quickly and
as comprehensively as possible. it's not a good book if you're a beginner
to programming or are looking for a pure reference like PER or Nutshell.
what do you think you are missing? is there something in the book that
you don't/can't understand? those of us on the list may be able to
help you out... sometimes humans are better at explaining things than
just books. :-)

input() must be avoided at all costs in Python 2.x. if you find any
Python (2.x) book which employs that, consider the author uninformed.
it is a huge security risk and the main reason why in Python 3
raw_input() is renamed to and replaces input().

sorry, make that "mutable." sets, dicts, and lists are standard Python
types that are mutable.

in addition to alan's obvious solution, if you wanted to roll your
own, you have a good start. my comments below.

in addition to the good advice from vince (watch out for greediness
regardless of what you're looking for) and bill (use raw strings...
regexes are one of their primary use cases!), another thing that may
help with the greediness issue are the character sets you're using

on a related note, there is a module called fileinput that doesn't do
what you (the OP) need for this particular problem, but it is one to
keep in mind for the future as there may be a situation for which it
is the right tool. it doesn't get a lot of buzz but can come in handy

rather than one-liners, we can try to create the most "Pythonic"

as i mentioned in my other msg, you need another break statement that
is *not* in another loop. in your case, not in the for-loop. you need
a break statement somewhere within your while block (again, that's not
in any other loop). IOW, it should be
