python --- 函数学习的准备

1 有关同学阿玲的game习题

2 语句即逻辑，结构即存储
if
while :
pass

for

数据结构:
dict
list
tuple

到固定地址获取数据思路步骤：

#geturl http://www.126.com#获取数据 urllib2    #1.访问网页         #访问不成功(log)         #访问成功    #2.#分析数据 正则 和 beautifulsoup#入库

3 virtualenv的使用
python的沙盒环境，参考http://www.cnblogs.com/zknublx/p/5953249.html
