This code

  for(i = 0; i < 10000; ++i) {
    std::ostringstream trial;
    FILE              *fp;

    trial << "dft_" << std::setw(5) << std::setfill('0') << i << ".py";
    //ierr = PetscExceptionTry1(PetscFOpen(PETSC_COMM_WORLD,
trial.str().c_str(), "r", &fp), PETSC_ERR_FILE_OPEN);
    ierr = PetscFOpen(PETSC_COMM_WORLD, trial.str().c_str(), "r", &fp);
    if (ierr == PETSC_ERR_FILE_OPEN) break;
    ierr = PetscFClose(PETSC_COMM_WORLD, fp);CHKERRQ(ierr);
  }

produces the following printout

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