I think the reason that there are so few examples is that many examples
exist in other packages, such as Firedrake, and they are the main
consumers. KSPPYTHON is a way to write KSPSHELL using Python rather than C,
and we mostly write C.
I will say that recently we fixed everything so that PETSc errors and
Python exceptions are passed correctly up the stack, and debugging these
things should be easy. I have been debugging the PyVista visualization, and
I can change the Python in one window and run in the other. It is easy.

What most experimenters take for granted before they begin their
experiments is infinitely more interesting than any results to which their
experiments lead.
