Answer 1

It actually depends on the Python driver that you are using to connect to Neo4j (check https://neo4j.com/developer/python/ to see the list of available drivers). If you are using the official neo4j-driver, the code you wrote is correct. In order execute the Cypher query, you could do something like this:

from neo4j import GraphDatabase

uri = # insert neo4j uri
user = # insert neo4j username
password = # insert neo4j password

n = "abc"
a = 1234
query = "CREATE (cornell:university { name: $n,yob:$a})"

driver = GraphDatabase.driver(uri, auth=(user, password))
session = driver.session()
result = session.run(query, n=n, a=a)
session.close()
driver.close()

Although âńōŋŷXmoůŜ's answer will probably work, it is not recommended way to it.
