python 爬虫爬取历年双色球开奖信息

目前写的这些爬虫都是些静态网页，对于一些高级网页（像经过JS渲染过的页面），目前技术并不能解决，自己也是在慢慢学习过程中，如有错误，欢迎指正；

对面前端知识本人并不懂，过程中如果涉及到前端知识，也是百度而来，毕竟爬虫还是和前端页面打交道多，前端知识还是要多学习；　

此篇还是继续静态页面，更换了不同的内容，以及涉及到多个python 模块和自己二次封装的模块，个人感觉这些模块不使用在爬虫方面也是很有用的；

第一部分，封装了自带模块logging，其中使用了getpass 模块，用来记录日志的用户名，都是些简单的使用，关于注释，本来已写好，并未上传到git，导致此次上传代码没有下次注意，哈哈；

个人建议：在学习python 过程中多练习写代码，在写的过程中去理解其中的用法；

import logging
import getpass

class MyLog(object):
    "this class will create log"
    def __init__(self):
        user = getpass.getuser()
        self.logger = logging.getLogger(user)
        self.logger.setLevel(logging.DEBUG)
        logFile = './progress.log'
        formatter = logging.Formatter(
            '%(asctime) -12s %(levelname)-8s %(name) -10s %(message)-12s'
        )
        '''logfile output screen and files'''
        logHand = logging.FileHandler(logFile)
        logHand.setFormatter(formatter)
        logHand.setLevel(logging.ERROR)
        logHandt = logging.StreamHandler()
        logHandt.setFormatter(formatter)
        self.logger.addHandler(logHand)
        self.logger.addHandler(logHandt)

        '''five level and five functions '''
    def debug(self,msg):
        self.logger.debug(msg)

    def info(self,msg):
        self.logger.info(msg)

    def warn(self,msg):
        self.logger.warning(msg)

    def error(self,msg):
        self.logger.error(msg)

    def critical(self,msg):
        self.logger.critical(msg)

if __name__ == "__main__":
    mylog = MyLog()
    mylog.debug('i am debug')
    mylog.info('i am info')
    mylog.warn('i am warning')
    mylog.error('i am error')
    mylog.critical('i am critical')

第二部分：使用了re,urllib2,xlwt,bs4,sys模块；xlwt模块在之前的博客里已写过；bs4　模块大名鼎鼎，不过多解析，至于为什么用它，因为其简单，其它的爬虫模块也不会；也在学习当中；

以上部分，也是学习了别人经验，也从代码中学到了不少知识，愿本文也能给你带来灵感；
