Python Modules for the Network Engineer
Parsing Data
Most Network devices/Tools will return and accept data in a serialised data format, the most common of which are XML and JSON.


Using the JSON module to parse returned data.


Converting returned XML to a Python Dictionary.


Easily manipulate and create YAML files.


Easily manipulate IPv4 and IPv6 addresses.

Connecting to the Network
Connectivity to networking devices is almost exclusively through SSH, therefore a robust SSH programming environment is required.
Most API calls to either orchestration platforms and networking devices (although not exclusively) are made through REST (Representational State Transfer).  An understanding of REST operations and the ability to program against it is an essential requirement of the Network Engineers toolbox.


Essential module to establish and maintain your SSH programming environment.


turbo charge SSH connectivity in Python.


Human friendly REST requests in Python.

Storing Data/Retrieving Data


Interact with Excel spreadsheets and CSV files.


Storing and retrieving data from MongoDB with python.


Retrieving user input data from the command line.



A module to cater for Regular Expression operations on data.


Templating language.

Cisco ACI
