Adding triplets to 4store
here url_add is a link that contains rdf triplets that I want to store in 4store.but, if I pass url_add as an argument it generates a Relative URIerror.
so I can only pass url_add as an argument.
response = store.add_from_uri ('url_add')
Traceback (last call last):

What is the value of your URL
This is an exception because you are passing in a relative url instead of an absolute one (you probably have something like "../../directory/filename.rdf"
If your url is an HTTP url (http: //host/filename.rdf) and dereferenceable , you can also use the LOAD directive as part of the SPARQL update. So it just means preempting a SPARQL query (just like you are doing a SPARQL query using 4store) using the following expression:
LOAD <http://host/filename.rdf>
INTO GRAPH <http://optional-name-of-graph>
