I'm tryng to use optparse for the first time. The toy summary is that I want to have the following command format:
prognam -f FORMAT Where FORMAT, if specified, must be one of "X", "Y", or "Z". In otherwords, if the user enters: progname -f X It runs, producing its output in format X. Similar if "Y" or "Z" is specified instead of "X". But if the user specifies progname -f A I want it to spit up because A is not a recognized format. I don't see anything in the docs that directly addresses this. Is this something that I should use the callback parameter for? _______________________________________________ Tutor maillist - [email protected] http://mail.python.org/mailman/listinfo/tutor
