当没有后续节点之后，但是又想使用clear:both，清楚float。 则可以通过这段代码，设置父节点的style
.clearfix:after {
content: ".";
display: block;
clear: both;
visibility: hidden;
line-height: 0;
height: 0;
}
.clearfix {

one-line tree in python

One-line Tree in Python

Using Python's built-in defaultdict we can easily define a tree data structure:

def tree(): return defaultdict(tree)

That's it!

一道面试题，具体见我的博客http://shihongzhi.github.com/。这里使用bjoern作为WSGI server,从reqeust的‘QUERY_STRING’中得到json数据。这里的stategys和actions变量保存了需要处理的策略和行为。limit_time为限制次数。 本程序有个问题，当数据特别大的时候，datas这个list会特别大，导致性能下降，可以考虑用队列替换list，定时删除那些过时的json数据
# --- coding:utf-8 ---
import strategy
import bjoern
from urlparse import parse_qsl
strategys = [strategy.strategy_highfreq, strategy.strategy_repetition]
actions = ['answer', 'comment', 'question']
limit_time = 10
datas = []
