前提条件是python操作excel和数据库的环境配置是完整的，这个需要在python中安装导入相关依赖包；
实现的具体代码如下：
#!/usr/bin/python
# -*- coding: utf-8 -*-
import urllib
import urllib2
import sys
import re
import ssl
import openpyxl
import MySQLdb
import time
#from bs4 import BeautifulSoup
#修改系统默认编码为utf-8
reload(sys)
sys.setdefaultencoding("utf-8")
ssl._create_default_https_context = ssl._create_unverified_context
