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.) https://www.python.org/dev/peps/pep-0465/ -- Steve “Cheer up,” they said, “things could be worse.” So I cheered up, and sure enough, things got worse. -- https://mail.python.org/mailman/listinfo/python-list
