Python uses the paramiko module to execute ssh commands in batches.

This article mainly explains how to use the paramiko module to execute ssh commands in batches in python. it has some reference value. interested friends can refer to multiple devices to execute ssh commands in batches. Currently, it is serial, multi-thread parallel implementation will be added later, and the source code will be directly added

Note that you cannot execute top or other dynamic commands.
