<h3>Advanced Python training course description</h3>
 This course caters to network engineers aiming to
enhance both their Python proficiency and network
automation skills. Delving deeper into key areas such
as netmiko, Nornir, and ncclient, we also focus on
automating network testing and validation. Participants
gain greater confidence working with Python functions,
classes, objects, and error handling. The course
additionally introduces more libraries like Scrapli, TTP,
pyATS, Genie, pybatfish, and Suzieq, which cover
parsing strategies, automation testing, validation,
network analysis, observability, and telemetry. The
curriculum also encompasses concurrency techniques.

REST and RESTCONF

<h3>Python training course description</h3>
 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, NAPALM and
Nornir, and APIs such as NETCONF and RESTCONF
rather than enabling delegates to produce object
oriented programs. Hands on sessions use Cisco and
Juniper devices.

<h3>Network management technologies course description</h3>
 A comprehensive tour of the available network
management technologies available for todays
networks. The course starts with basic tools such as
syslog along with Python network automation. SNMP is
then covered with the *flow technologies and streaming
telemetry. Configuration management with ansible,
Python, NETCONF and RESTCONF is then studied.
The final part of the course looks at SDN. Hands on
sessions are used throughout to reinforce the theory
rather than teach specific manufacturer equipment.
Note that sections are available as individual courses.
