I don't think that @@ means anything yet.
There was a proposal to use @@ for matrix exponentiation in Numpy, as @ is
used for matrix multiplication, but that was left on hold to see whether it
is really needed or not.
Where did you find @@ in Python?
(By the way, @ for matrix multiplication only works in Python 3.5 or better.)
