Description: ****************************
        Neo4j Bolt Driver for Python
        ****************************
        
        This repository contains the official Neo4j driver for Python.
        Each driver release (from 4.0 upwards) is built specifically to work with a corresponding Neo4j release, i.e. that with the same `major.minor` version number.
        These drivers will also be compatible with the previous Neo4j release, although new server features will not be available.
        
        + Python 3.9 supported.
        + Python 3.8 supported.
        + Python 3.7 supported.
        + Python 3.6 supported.
        
        Python 2.7 support has been dropped as of the Neo4j 4.0 release.
        
        
        Installation
        ============
        
        To install the latest stable version, use:
        
        .. code:: bash
        
            pip install neo4j
        
        
        Quick Example
        =============
        
        .. code-block:: python
        
            from neo4j import GraphDatabase
        
            driver = GraphDatabase.driver("neo4j://localhost:7687", auth=("neo4j", "password"))
        
            def add_friend(tx, name, friend_name):
                tx.run("MERGE (a:Person {name: $name}) "
                       "MERGE (a)-[:KNOWS]->(friend:Person {name: $friend_name})",
                       name=name, friend_name=friend_name)
        
            def print_friends(tx, name):
                for record in tx.run("MATCH (a:Person)-[:KNOWS]->(friend) WHERE a.name = $name "
                                     "RETURN friend.name ORDER BY friend.name", name=name):
                    print(record["friend.name"])
        
            with driver.session() as session:
                session.write_transaction(add_friend, "Arthur", "Guinevere")
                session.write_transaction(add_friend, "Arthur", "Lancelot")
                session.write_transaction(add_friend, "Arthur", "Merlin")
                session.read_transaction(print_friends, "Arthur")
        
            driver.close()
        
        
        Connection Settings Breaking Change
        ===================================
        
        + The driver’s default configuration for encrypted is now false (meaning that driver will only attempt plain text connections by default).
        
        + Connections to encrypted services (such as Neo4j Aura) should now explicitly be set to encrypted.
        
        + When encryption is explicitly enabled, the default trust mode is to trust the CAs that are trusted by operating system and use hostname verification.
        
        + This means that encrypted connections to servers holding self-signed certificates will now fail on certificate verification by default.
        
        + Using the new `neo4j+ssc` scheme will allow to connect to servers holding self-signed certificates and not use hostname verification.
        
        + The `neo4j://` scheme replaces `bolt+routing://` and can be used for both clustered and single-instance configurations with Neo4j 4.0.

        Connecting with Python Driver 4.x to Neo4j 3.5
        ----------------------------------------------
        
        Using the Python Driver 4.x and connecting to Neo4j 3.5 with default connection settings for Neo4j 3.5.
        
        .. code-block:: python
        
            # the preferred form
        
            driver = GraphDatabase.driver("neo4j+ssc://localhost:7687", auth=("neo4j", "password"))
        
            # is equivalent to
        
            driver = GraphDatabase.driver("neo4j://localhost:7687", auth=("neo4j", "password"), encrypted=True, trust=False)
        
        
        Connecting with Python Driver 1.7 to Neo4j 4.x
        ----------------------------------------------
        
        Using the Python Driver 1.7 and connecting to Neo4j 4.x with default connection settings for Neo4j 4.x.
        
        .. code-block:: python
        
            driver = GraphDatabase.driver("neo4j://localhost:7687", auth=("neo4j", "password"), encrypted=False)
