Episode Description:
You're writing Python code to solve your network configuration and operational challenges. You've mastered libraries like Netmiko, ncclient, and requests. You can manipulate XML, JSON and YAML like a pro. You've saved yourself and your organization hours with your work, but you're still a bit embarrassed by your code... Don't worry, you are not alone.

Most network engineers didn't start as developers, we kinda just learned as we went, hacking together something that "worked". In this session you'll learn simple coding skills and techniques that you can use today to make your code something you'll be proud to share and show off.
