INSERT/DELETE/UPDATE query using SPARQLWrapper

Question

Although I have gone through lot of examples on the web explaining the use of python SPARQLWrapper using SELECT statements for fetching data from sesame triple store, but no

Answer 1

This is not particularly clear from the docs, but I think you can just execute an update statement in the same way that you execute a query:

queryString = "DELETE WHERE { ?s ?p ?o. }" 
sparql = SPARQLWrapper("http://localhost:8080/openrdf-sesame/repositories/test/statements")

sparql.setQuery(queryString) 
ret = sparql.query()

In the case of Sesame, one thing to keep in mind is that the URL for the update endpoint (repositories//statements) is not the same as the URL for the query endpoint (repositories/). See the Sesame protocol docs for details.
