I suspect it's not. The code is largely written in C and C++ and what I can see of the package on Github makes it look like it's the version of SuiteSparse with CMake as the build system. I realise my comment may have come off a bit flippant - it wouldn't be a trivial piece of work to write Python bindings for SuiteSparse, but would conceivably be simpler than trying to write a better sparse matrix algebra implementation.
