That is not the case: the commands ‘true’ (returns value 0) and ‘false’ (returns value 1) are long established in Unix. So that *is* part of the meme I'm describing. > None of the above is a good reason to use error *or* success return > values in Python--use exceptions!--but may be encountered when running > other processes. Right. But likewise, don't deny that “true == 0” and “false == non-zero” has a wide acceptance in the programming community too. -- \ “Program testing can be a very effective way to show the | `\ presence of bugs, but is hopelessly inadequate for showing | _o__) their absence.” —Edsger W.
