Adding a python list parameter in a neo4j query

Question

I'm about to run a query in neo4j with a parameter, but it always returns me an error.

> query= ("MATCH (p1:Item),(p2:Item) where p1.value=$name
> RETURN  p1.value AS from, p2.value AS to,
> gds.alpha.similarity.euclideanDistance((p1.embeddingNode2vec),
> (p2.embeddingNode2vec)) AS similarity order by similarity desc limit
> 40", name=references[2])

the p1.value the first element in the references list. This returns me a

SyntaxError: invalid syntax

error. Could you please tell me how to run it? my research so far: https://community.neo4j.com/t/how-to-use-dictionary-parameters-in-python-neo4j/18626

Answer 1

MATCH (p1:Item),(p2:Item) where p1.value=$params RETURN  p1.value AS from, p2.value AS to, gds.alpha.similarity.euclideanDistance((p1.embeddingNode2vec), (p2.embeddingNode2vec)) AS similarity order by similarity desc limit 40

and then call the query execution like this:

nodes = graphDB_Session.run(query, params= references[1])
