Assertion Error from creating RDF form using triple store

[Sithara K]

I'm new to python. I tried to create RDF form using triple store.

store=TripleStore()

But I'm getting this error

File "<pyshell#3>", line 1, in <module>
store=TripleStore()
File "C:\Users\Administrator\Desktop\TripleStore.py ", line 13, in __init__
super(TripleStore, self).__init__(backend=backend)
File "build\bdist.win32\egg\rdflib\Graph.py", line 1008, in __init__
super(BackwardCompatGraph, self).__init__(store=backend)
File "build\bdist.win32\egg\rdflib\Graph.py", line 815, in __init__
assert self.store.context_aware, ("ConjunctiveGraph must be backed by"
AssertionError: ConjunctiveGraph must be backed by a context aware store.

Please Help
