This Python course focusses on teaching Python for use in network automation and network DevOps.
We focus on getting delegates up and running with Python and network automation as quickly as possible rather than making them great programmers. In other words we concentrate on enabling delegates to use network automation libraries such as netmiko and NAPALM and APIs such as NETCONF rather than enabling delegates to produce object oriented programs.
Hands on sessions use Cisco and Juniper devices.
TCP/IP foundation for engineers
By the end of the course delegates will be able to:
