He means that in most cases what you want to do is probably capture the stdin & out. it's not obsolete, it's just not that common of a case. I'm not sure why he used that term. Most people tend to use popen because it's more useful. However, os.popen _is_ obsolete, or at least discouraged; the correct module to use is the subprocess module, as I mentioned earlier. _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
