Python optparse not working - syntax error -


this script based on assignment. code looks same theirs , both error out syntax error. running activestate active python 2.7 64-bit

def showevents():     ''' showevents command      list events event logger following options:     -t or -type (type of event search for)         warning (default option)         error          information             -g or -goback (time in hours search)         integer         default 100 hours      >>>showevents -t warning -g 100     type =  warning     goback = 100 hours     '''     import optparse      parser = optparse.optionparser()     parser.add_option('-t', '--type', \                         choices=('error', 'warning', 'information', 'all' ), \                         help='write type eventtype',                          default = 'warning')     parser.add_option('-g', '--goback', \                         help='write goback goback',                         default = '100')     (options, args) = parser.parse_args()     return options  options = showevents()  print 'type = ', options.type print 'goback =', options.goback, 'hours'  if options.type == 'all': if options.goback == '24':     import os     os.startfile('logfile.htm')

this returns defaults when runs, wont accept input. have missed?

>>> type =  warning goback = 100 hours >>> showevents -t error traceback (  file "<interactive input>", line 1     showevents -t error                   ^ syntaxerror: invalid syntax >>>

thanks looking.

the problem isn't code, way you're trying test it.

showevents -t error not valid line of python, is valid line of sh or cmd.

so, don't type python interpreter, type bash/dos prompt in terminal/dos window.

also, if you're not on windows, script have saved showevents (rather showevents.py), , have installed somewhere on path, , have have executable flag set, , need #!/usr/bin/env python or similar first line. (or can skip , type python showevents.py -t error @ bash prompt.)

on windows, can call showevents.py; long you're cd'd same directory it's saved in it's automatically on path; , there no executable flag or shebang line worry about.
