The Couchbase Python SDK allows Python applications to access a Couchbase cluster. The Python SDK uses the high-performance C library libcouchbase to handle communicating to the cluster over Couchbase’s binary protocols.

from couchbase.cluster import Cluster
from couchbase.auth import PasswordAuthenticator

cluster = Cluster('couchbase://localhost', authenticator=PasswordAuthenticator('username', 'password'))
bucket = cluster.bucket('default')
coll = bucket.default_collection()


coll.upsert('key', 'value')
get_res = coll.get("key")
print('Get result - value: {}; CAS: {}'.format(get_res.content, get_res.cas))

# Output:
# Get result - value: value; CAS: 1617046112012992512

Couchbase Python SDK 3.2

Getting Started

Dive right in with a quick install and Hello World. Try out our Travel Sample Application. And take a look at the developer preview of Collections.

Practical Howto Docs

Connect to our services — data (KV); Query; Search; Analytics — and the Sub-Document API.

Reference Guides

The documentation supplements the practical Howto docs with references and concept guides, for those who prefer a broader understanding before diving in and coding.

What’s Hot?

The Couchbase Python SDK 3.x is a complete rewrite of the API, reducing the number of overloads to present a simplified surface area, and adding support for future Couchbase Server features like Collections and Scopes (available in Couchbase Server 6.5 & 6.6 as a developer preview).

The 3.x Python SDK introduces comprehensive PEP-484-style type annotations.
