Solution

  • Below is the syntax on passing parameters in neo4j python driver. Unfortunately, you cannot use labels or relationship types in the parameter. If you need to pass labels (like Human:Moviestar) then you can use string function in python like this: passing parameters in neo4j using python

    name = "Tom Cruise"
placeOfBirth = "Syracuse, New York, United States" 
query = "Create (n:Human:Moviestar { name: $name, placeOfBirth: $placeOfBirth})"
session = driver.session()
result = session.run(query, name=name, placeOfBirth=placeOfBirth)
