Hi,
We have written a Python module to perform shear-wave splitting based on SplitLab, which uses obspy classes and methods. We will make it available via a Git repository as soon as we can. For reference, it was used in the following paper:
https://pubs.geoscienceworld.org/geology/article/44/10/807/195028/?searchresult=1
Output examples are described here:

We will post the link to the repository here in the near future.
Cheers
Pascal Audet & Andrew Schaeffer
