Running SPARQL Queries on turtle file

I’m trying to run SPARQL queries on turtle files using python, but my sparql returns all the entries, how can I return the entry with name=”Idham Al-Taif Mahmoud”?

turtle file:

python code:

import rdflib

filename = "turtle.ttl"


g = rdflib.Graph()

result = g.parse(filename, format='ttl')
print(result)

query = """

SELECT ?person
WHERE {
    ?person <http://dbpedia.org/ontology/hasName> "Idham Al-Taif Mahmoud"
}

"""

g.query(query)
for stmt in g:
    print(stmt)

Answer

I think your issue is with the methods. Here is a link with a nice example of what you want to do.

The following script works for me:

import rdflib
  
filename = "turtle.ttl"


g = rdflib.Graph()

g.parse(filename, format='ttl')

query = """

SELECT ?person
WHERE {
    ?person <http://dbpedia.org/ontology/hasName> "Idham Al-Taif Mahmoud"
}

"""

qres = g.query(query)

for row in qres :
        print("%s" % row)

Notice that I assign the results of the query to a new variable qres, and also that the parse method is void, i.e. it does not return a value like you had.

The % signs in the end are just to print a human readable result, but you can totally get rid of them.
