Calling RESTCONF with Python

This example script uses the requests Python library to interact with a RESTCONF Agent.

This Python script leverages RESTCONF to:

retrieve a list of interfaces on a device
ask the user for the interface to configure
displays the interface IP information
asks user for new IP information
updates the IP address on the interface
displays the final IP information on the interface

This script has been tested with Python 3.7, however may work with other versions.

DevNet Sandbox

This script targets the RESTCONF DevNet Sandbox that leverages a CSR1000v as a target.

Find details on the Sandbox here.

To execute this script against a different device, update the variables that list the connectivity, management interface, and url_base for RESTCONF.
