is there a way to parameterize a sparql filter condition?

Question

I am trying to find out what is the best way to parameterize a filter condition with a float value taken as input.

count=25.67
FILTER(?price < count)

instead of:

FILTER ( ?price < 25.67 )

The value of "count" will be taken as input.

I would like to know the syntax for including the object count in the FILTER command.

Thank you in advance.

Here's an example of setQuery use with a parameter added via `.format():

from SPARQLWrapper import SPARQLWrapper, JSON


def query_dbpedia(my_uri)
    sparql = SPARQLWrapper("http://dbpedia.org/sparql")
    q = """
        PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>

        SELECT ?label
        WHERE {{
            {} rdfs:label ?label .
        }}
    """.format(my_uri)
    sparql.setQuery(q)
    sparql.setReturnFormat(JSON)
    results = sparql.query().convert()

    results_to_return = []
    for result in results["results"]["bindings"]:
        results_to_return.append(result["label"]["value"])

    return results_to_return

print(query_dbpedia("http://dbpedia.org/resource/Asturias"))
