[petsc-users] Calling PETSc functions from Python using petsc4py

[Larson, Jeffrey M.]

Hello,

Is there a way to call a function in a PETSc example file from python?

Explicitly, I'd like to call EvaluateFunction and EvaluateJacobian (resp. lines 
123 and 147) of 
https://www.mcs.anl.gov/petsc/petsc-current/src/tao/leastsquares/examples/tutorials/chwirut1.c.html
from Python.

Can petsc4py version 3.7.0 help with this?

Thank you for your help,
Jeffrey Larson
