I decided to take Kirk's courses on Ansible and Nornir during the stay-at-home-orders in 2020 when COVID-19 hit the world. After the first few lessons I was able to write my first script to check for and add VLANs to our NX-OS environment.Stian LiebenbergSenior Wireless Engineer
I have taken several paid and non-paid Python courses. I can say that by far your course is the best one I have taken. The way you explained stuff just makes sense to me.Joli MartinezAutomation Engineer
I am on the material for the 3rd week and I just wanted to compliment you on the way that you explained how to unwrap the data structures. Best step by step explanation I have seen so far to help me understand and work with the data. Thank you very much!Ray deGuzmanSenior Network Engineer

What is the format of the course?
The course is a ten week email-course. Each week you will receive a lesson that contains a set of videos, some additional content, and some exercises. I will post solutions to the exercises online. Both the Plus and the Premium Package have a community forum where you can ask questions, post code, and interact with me and with the other students.
Is there a lab environment?
Yes, the lab environment will consist of a set of virtual and physical network devices and at least one AWS-Linux server. I will install a set of libraries in the lab environment; this will enable you to get working quickly. From the lab environment you will be able to use Netmiko, Arista's eAPI, NAPALM, NX-API, and Juniper's PyEZ.
What are the prerequisites for the course?
You should be familiar with the basics of Python. You can be slow at writing Python code, but these ideas should not be new to you.
You also need to be familiar with basic network engineering (routing, switching, SNMP, Cisco CLI configuration).
Finally, since the lab environment will use Linux. You should be at least somewhat familiar with Linux. You should know the basics of how to move around the file system, execute a script, and edit a file.
Python facilitates writing clean, readable code and is natively present on Linux and MacOS. Python has gained widespread support in the networking community both from engineers and from vendors. Python has a large, active community and, consequently, numerous resources are available to you (libraries, documentation, books, tutorials, etc.).
What is the community forum?
The community forum is a forum where students can interact, post code, ask questions, and make recommendations. Students that purchase either the Plus or the Premium Package will have access to the community forum for the duration of the course.
What if I am unsatisfied with the course after I sign-up?
If you are not satisfied with the course, there is a 30-day money back guarantee. No questions asked.
