通过邮件定时发送天气预报给自己

linewer

  最近天气一直不正常,用python写了个简单的脚本(够丑的)定时给自己发天气邮件(以前写过一个perl的，不知放哪去了).网上也有好些例子可以参考，好些人借助Fetion发天气短信(这个挺好）但由于我现在用联通的号，一时也用不了......

#FileName:     weather_broadcast.py
#Description:  automatically get the weather information from internet,deal with it and send it out everyday to my sisters,best friends and myself^_^.  Actually, It can be sent out as short messages by the ChinaMobile Fetion which will be useful(Because of some reasons, I use chinaunicom now. I use email everyday,so it's enough for me...)

#Now there are still 2 things to be done:
#(1).dealing with the IOError and socket.gaierror
#(2).Write a class to include the all functions
