Yours is the same as Tim's, it can't handle a word with two or more
brackets pairs, too.
I tried to change the "\S*\([^\)]*

sorry i forgot to give a limitation: if a letter is next to a bracket,
they should be considered as one word. i.e.:
"a(b c) d" becomes ["a(b c)", "d"]
because there is no blank between "a" and "(".

I've got some strings to split. They are main words, but some words
are inside a pair of brackets and should be considered as one unit. I
prefer to use re.split, but haven't written a working one after hours
of work.
Example:
"a (b c) d [e f g] h i"
should be splitted to
["a", "(b c)", "d", "[e

Are you sure you have setup the environment variables before you build?
Here is a reference: "Building Python Extensions with the MS Toolkit
Compiler" (http://www.vrplumber.co
has an "append" method). You can use "print addr" or "print repr(addr)"
to determine that.

Is addr is really a string? AFAIK, strings havn't an append methond.
use += to extend strings:
.>>> addr = 'abc'
.>>> addr += '%s;'
.>>> addr
'abc%s;'

ery sorry to take you too much effort on this
weird code. I should make it clear that there is only *one* thread (the
main thread in my application) calls the get_data() method,
periodically, driven by a timer. And fo
t very sure about the get_data() method. Will it cause data lose
if there is a thread is appending data to self.data at the same time?
Is there a more pythonic/standard recipe to collect thread data?
