delete rest api to remove statements from global context

问题

I send the following http request to Sesame Server:

params = { 'subj' : '?s', 'pred' : 'rdf:type', 'obj' : 'Device' }

Also tried:

params = { 'pred' : 'rdf:type', 'obj' : 'Device' }

which translates to:

http://example.com/openrdf-sesame/repositories/devices/statements?pred=rdf%3Atype&subj=%3Fs&obj=Device

I perform following operation on params in PYTHON:

 urllib.urlencode(params))

I get Response: 400 (Bad Request).

Please help resolving this issue. I think its related to improper encoding of predicate URI. The prefix is: '<http://example.com/devices#>'

You need to provide full URIs for the request parameters. Prefixed names are not allowed. The full URIs should be in N-Triples encoded form (that is, enclosed in angle brackets).
