Using Python in Network Engineering: Preparing for the future beyond 2020

Why do I need to learn Python programming I am already enjoying subnetting, routing, and switching?  Everything has already been automated, I do not need to write any code. Software-based technologies are already being implemented.

1. COMPLEX NETWORKS. Since networks are now becoming more complex, the challenge is for the network engineer to be able to keep up with all these changes which are now going beyond what is traditionally been practiced. Network Engineers must be able to deal with scales of networks, rate of change and processing of requirements which would require them to know the basics of Python programming and move towards specific skills and tools that are needed for you to be able to manage everything in the network.

2. FOUNDATION OF NETWORK AUTOMATION. The future of Network Engineering is not just in being able to use the Subnet Calculator. The challenge for the Network Engineer is to be able to understand configuration at a deeper level.  This is the reason why you have to learn how to use Python to modify and curate scripts, query the APIs for the network controllers, management systems and devices, and be able to the foundation of network automation for Open Source projects.
