Network automation is something that can bring a lot of efficieny in an environment where network infrastructure is large and there are tasks that are performed repeatedly on regular basis, if humans are performing those tasks then there is always a space for human error, but if we automate them then it reduces the room for those errors. It can also reduce the operating cost of network by automating those tasks that are usually performed manually.

Beside that, It also enhances the security by ensuring the policy enforcement. There are many such things that can be implemented in the network like we can automate the process of getting alerts when a User is logged-in on any critical node and so on.

As for the programming language, Python is a popular option for network automation because of its library ecosystem and simplicity.

The implementation of network automation using python should include different stages, like, it should be tested in lab environment first before using it in production environment. Obviously, No one is going to make those mistakes, but, I just wanted to write that, because why not.
