How does Py2Neo use parameters to make repeat queries faster?

I am trying to make a simple API to interact with my database. Given input of an ID look up I want to return a subgraph of all related Ids. My question is how can I parameterize this in Py2Neo so I use the same query execution plan in Cache to speed up the API. I have seen how to do this in Cypher and Cypher-shell. Wondering what it takes to do this in Py2Neo..

There are several functions in py2neo that take a statement and parameters

e.g.

github.com

neo4j-examples/movies-python-py2neo/blob/master/example.py#L51-L54


      
          results = graph.run(
              "MATCH (movie:Movie) "
              "WHERE movie.title =~ {title} "
              "RETURN movie", {"title": "(?i).*" + q + ".*"})
