New submission from Qiangning Hong:
Integers, strings, and bool's hash are all consistent for processes of a same
interpreter. However, hash(None) differs.
$ python -c print(hash(None))
272931276
$ python -c print(hash(None))
277161420
It's wired and make difficulty for distributed systems

How can you prevent self from being passed to a function stored as a

That's bad form. If you insist on doing something like this, at least
use isinstance(a, str) instead of typeof. But even that breaks duck
typing; if a is a unicode string, that'll fail when the function may

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 f g],
faulkner wrote:
re.findall('\([^\)]*\)|\[[^\]]*|\S+', 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 (.

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*\([^\)]*\)\S*

Ah...the picture is becoming a little more clear:
r = re.compile(r'(?:\([^\)]*\)|\[[^\]]*\]|\S)+')
r.findall(s)
['(a c)b(c d)', 'e']
It also works on my original test data, and is a cleaner regexp
than the original.
The clearer the problem, the clearer the answer. :)
