Some rather unexpected behavior in the set_default/set_defaults methods for OptionParser that I noticed recently:
>>> import optparse >>> parser = optparse.OptionParser() >>> parser.add_option("-r", "--restart", dest="restart", action="store_true") <Option at 0x-483b3414: -r/--restart> >>> parser.defaults {'restart': None} >>> parser.set_default("retart", False) >>> parser.defaults {'retart': False, 'restart': None} Why does set_default not raise an exception when passed a key that it doesn't recognize? Bad typysts bewaer. The only reason I can think not to raise an exception is so that defaults can be defined before the options are added. Is there some use case that I'm not thinking of here? I realize that changing this could break some existing scripts, but I'm still tempted to file this as a bug. Mike -- http://mail.python.org/mailman/listinfo/python-list
