****************************
Neo4j Bolt Driver for Python
****************************
This repository contains the official Neo4j driver for Python.
Starting with 5.0, the Neo4j Drivers will be moving to a monthly release
cadence. A minor version will be released on the last Friday of each month so
as to maintain versioning consistency with the core product (Neo4j DBMS) which
has also moved to a monthly cadence.
As a policy, patch versions will not be released except on rare occasions. Bug
fixes and updates will go into the latest minor version and users should
upgrade to that. Driver upgrades within a major version will never contain
breaking API changes.
See also: https://neo4j.com/developer/kb/neo4j-supported-versions/
+ Python 3.13 supported (since driver version 5.26.0).
+ Python 3.12 supported (since driver version 5.14.0).
+ Python 3.11 supported (since driver version 5.3.0).
+ Python 3.10 supported.
+ Python 3.9 supported.
+ Python 3.8 supported.
+ Python 3.7 supported.
Installation
============
To install the latest stable version, use:
.. code:: bash
pip install neo4j
.. TODO: 7.0 - remove this note
.. note::
``neo4j-driver`` is the old name for this package. It is now deprecated and
and will receive no further updates starting with 6.0.0. Make sure to
install ``neo4j`` as shown above.
Alternative Installation for Better Performance
-----------------------------------------------
You may want to have a look at the available Rust extensions for this driver
for better performance. The Rust extensions are not installed by default. For
more information, see `neo4j-rust-ext`_.
.. _neo4j-rust-ext: https://github.com/neo4j/neo4j-python-driver-rust-ext
Quick Example
=============
.. code-block:: python
from neo4j import GraphDatabase, RoutingControl
URI = "neo4j://localhost:7687"
AUTH = ("neo4j", "password")
def add_friend(driver, name, friend_name):
driver.execute_query(
"MERGE (a:Person {name: $name}) "
"MERGE (friend:Person {name: $friend_name}) "
"MERGE (a)-[:KNOWS]->(friend)",
name=name, friend_name=friend_name, database_="neo4j",
)
def print_friends(driver, name):
records, _, _ = driver.execute_query(
"MATCH (a:Person)-[:KNOWS]->(friend) WHERE a.name = $name "
"RETURN friend.name ORDER BY friend.name",
name=name, database_="neo4j", routing_=RoutingControl.READ,
)
for record in records:
print(record["friend.name"])
with GraphDatabase.driver(URI, auth=AUTH) as driver:
add_friend(driver, "Arthur", "Guinevere")
add_friend(driver, "Arthur", "Lancelot")
add_friend(driver, "Arthur", "Merlin")
print_friends(driver, "Arthur")
