In this video, we're going to learn how to use the Python threading module to executecommands concurrently on multiple devices. This will allow us to create network automation scripts that are fast and efficient.

Netmiko is a powerful network automation platform that makes it easy to create and manage network commands. In this video, we're going to learn how to use the Python threading module to create network automation scripts that are fast and efficient.
