[Baypiggies] Python way to avoid usage of raise

[Nick S Kanakakorn]

There is a happy news here today.  The use of raise exception is allowed
again after I put some coding in using this convention:

exitcode, actual_result = f1()
if exitcode < 0: return exitcode
.... continue something useful with actual_result
exitcode, actual_result = f1()
