Python for Network Automation

Description

Overview:

This course is driven by demonstration and reinforced by hands-on labs for learning Python for Network Automation. Maximize your networking skill set by learning to script solutions to tedious, complex and oftentimes overwhelming networking tasks.

Prerequisite(s):

Keyboard proficiency, and some basic understanding of network concepts is the only hard requirement. Students with some previous exposure to Python, any another scripting experience, will take the most from the course. In lieu of any scripting experience, Alta3 Research’s Python Basics course is recommended.
