pip install neo4jAlternative 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.
Quick Example
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")Further Information
