You can find the library name on PyPI.

Solution

The correct answer is neo4j.

shell
pip install neo4j

Create a new driver instance

Great work! With the driver installed, you can now create a new driver instance.

Complete the code below to create a new driver instance.

python
from neo4j import GraphDatabase

NEO4J_URI = "neo4j://localhost:7687"
NEO4J_USERNAME = "neo4j"
NEO4J_PASSWORD = "letmein"

driver = GraphDatabase.#select:driver(
    NEO4J_URI,
    auth=(NEO4J_USERNAME, NEO4J_PASSWORD)
)

  • ❏ connect(

  • ✓ driver(

  • ❏ GraphDatabase(

  • ❏ new_driver(

Hint

What is the name of the object used to connect a Neo4j instance?

Solution

The method to create a new connection is GraphDatabase.driver().

shell
driver = GraphDatabase.driver(
    NEO4J_URI,
    auth=(NEO4J_USERNAME, NEO4J_PASSWORD)
)

Summary

You can now install the neo4j library and connect to Neo4j by creating a new driver instance.
