在其他模块或文件中调用：

 

import datetime
from Sendmailpro import PySendMail

today = datetime.date.today().strftime("%A (%a) %d/%m/%Y") 
m=PySendMail('jack','password','smtp.gmail.com','jack <jack@gmail.com>')
m.sendmail('jack@gmail.com','GEGW DB Report of '+today,'GEGW','plain','application/octet-stream','/tmp/result.txt',1,0)
