Python for Network & System Administrators

SS Course: GK8431

Course Overview

TOP

Targeted for network administrators looking to automate administrative tasks across a set of distributed clients Python for Network Administrators is an introductory and beyond-level practical, hands-on Python training course that leads the student from the basics of writing and running Python scripts to more advanced features such as file operations, regular expressions, working with binary data, and using the extensive functionality of Python modules with a focus on network-focused modules such as SSH, Git, and RESTful services. This comprehensive, practical course provides an in-depth exploration of working with the programming language, not an academic overview of syntax and grammar. Students will immediately be able to use Python to complete these types of tasks in the real world.
