stackoverflow上Python相关回答整理翻译(相对来说都比较简单/散，非系统学习用途，个人整理而已)

    当前进度: 90%

    问题个数: 135

    最后更新: 2014-10-04

查看了下前面(vote前15页,挑了下,vote都是100+的样子,大概200个)的问题，[链接](http://stackoverflow.com/questions/tagged/python?page=1&sort=votes&pagesize=15)

第一页的前几个比较长，目测都有中文翻译版本，大家可以网上搜下

如果有兴趣，可以一起翻译

注意，合并了每个问题的多个答案，但是时间仓促，疏漏难免，感兴趣问题直接点链接看原文吧
