> from qutip import *
For context about what this library is:
qutip is a library that makes the use of Dirac like notation much easier (i.e. to compute the inner product on <-y| and |+z> just define the quantum objects Smy and Spz and do Smy.dag () * Spz)
It will be effective if the Qutip package comes with SAGE.
