# using python 3
pip install pynessie


When you install pynessie, you get the Python client along with a Python CLI. Configuration for both is covered in our reference for the command line interface.


pynessie CLI has been deprecated in favor of the new Nessie CLI/REPL tool!


To instantiate a client simply run

from pynessie import init
client = init() # this will look for the client config as per above
branches = client.list_branches()

All endpoint options are available from this client.

Spark usage from Python

A common way to interact with Nessie is via Spark. You can read more about working with Nessie, Spark and Iceberg together on our Iceberg Client docs page.
