利用python脚本程序监控文件被修改

需求：

利用python编写监控程序，监控一个文件目录，当目录下的文件发生改变时，实现有修改就发报警邮件

邮件使用QQ邮箱，需要开启smtp，使用手机发生短信，腾讯会给你发邮箱密码。如下所示：

把这个密码填到程序中。

        send(content,title,froms,to)
        print (content)

    vm = pyinotify.WatchManager()
    vm.add_watch(path,pyinotify.ALL_EVENTS,rec = True)
    event = MyEvent()
    notifier = pyinotify.Notifier(vm,event)
    notifier.loop()
main(path)
