I might be wrong on this. Your point is extra true for modules in the standard library (which is what we're talking about for argparse). I just think that if a parser error is causing the SystemExit, I would rather catch a parser error than catching a SystemExit for the sake of readability. It saves me the comments: # Catching SystemExit because parse_args() throws SystemExit on parser errors. # Subclassing ArgumentParser and overriding exit because I don't want to exit() upon parser errors. So I'm sorry if what I said was irrelevant. I've never written or taken part of writing a std-lib module. --yuv _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
