Python for Systems Engineers - Part 3

Python is one of the most popular programming languages of our time and the powerhouse behind most of Cisco’s API efforts. If there is a Cisco API chances are high that there will be a software development kit for that API in python. In this 3-part webinar series we will get our hands dirty with python.

In Part 3 we will get our hands dirty building a chat bot in Webex Teams.
