Practical automated operation and maintenance Python script sharing

This article mainly introduces the sharing of practical automated operation and maintenance Python scripts. It has certain reference value. Now I share it with everyone. Friends in need can refer to it

./sendmail.py "topic" "hello world" "14638852@qq.com"

smtp and email signature, as well as the sender are fixed values ​​and need to be modified by yourself.
