How to insert data into named graph using SPARQL?

I am using python to insert data into blazegraph. I want to specify the named graph to which the data gets inserted, but the code I am using is triggering the error:

SPARQLWrapper.SPARQLExceptions.QueryBadFormed: QueryBadFormed: a bad request has been sent to the endpoint, probably the sparql query is bad formed.

How can I solve this error and insert data into the given named graph?

from SPARQLWrapper import SPARQLWrapper, JSON, TURTLE, RDFXML

query='''
PREFIX dcterms: <http://purl.org/dc/terms/>

INSERT DATA {
    GRAPH <http://example/shelf_A> {
        <http://example/author> dcterms:name "author" .

        <http://example/book> dcterms:title "book" ;
                              dcterms:author <http://example/author> .  
    } 
}
'''

sparql =SPARQLWrapper("http://localhost:9999/blazegraph/namespace/kb/sparql")

sparql.setQuery(query)
sparql.method = 'POST'
sparql.query()

I also tried running this query from the update tab of blazegraph and the same error happens. What am I doing wrong?
