How to insert data in Neo4j graph database

Below is an example of how to insert data into a Neo4j database using the official Neo4j Python driver called neo4j. Before running this code, make sure you have Neo4j installed and running on your local machine or a remote server.

from neo4j import GraphDatabase

Define the Neo4j connection URI and credentials

uri = "bolt://localhost:7687"

username = "your_username"

password = "your_password"

Define a function to insert data into Neo4j

def insert_data(tx, name, age):

    tx.run("CREATE (p:Person {name: $name, age: $age})", name=name, age=age)

Main function to connect to Neo4j and insert data

def main():

     Connect to the Neo4j database

    with GraphDatabase.driver(uri, auth=(username, password)) as driver:

         Start a session

        with driver.session() as session:

             Define some sample data

            data = [("Alice", 30), ("Bob", 25), ("Charlie", 35)]

             Insert each data point into Neo4j

            for name, age in data:

                session.write_transaction(insert_data, name, age)

            print("Data inserted successfully!")

Run the main function

if __name__ == "__main__":

    main()

This code snippet does the following:

1. Imports the GraphDatabase class from the neo4j package.

2. Defines the Neo4j connection URI, username, and password.

3. Defines a function insert_data to insert a person node with properties (name, age) into Neo4j.

4. Defines a main function that connects to the Neo4j database, starts a session, defines some sample data, and inserts each data point into Neo4j using a transaction.

5. Runs the main function when the script is executed.

Make sure to replace "bolt://localhost:7687", "your_username", and "your_password" with your actual Neo4j connection details. You can modify the data list to insert different data points into Neo4j.
