My template for a Python starter script

#!/usr/bin/env python """This describes how to use the script. This script docstring documents the script and will also be printed by exit_with_usage() if there is a problem or if the user requests help (-?, --help, etc.). $Id$ """ import sys, os, traceback import re import getopt from pexpect import run, spawn def exit_with_usage(): print globals()['__doc__'] os._exit(1) def parse_args (options=None, long_options=None): try: optlist, args = getopt.getopt(sys.argv[1:], options+'h?', long_options+['help','h','?']) except Exception, e: print str(e) exit_with_usage() options = dict(optlist) if [elem for elem in options if elem in ['-h','--h','-?','--?','--help']]: exit_with_usage() return (options, args) def main (): (options, args) = parse_args('v') # if args<=0: # exit_with_usage() if '-v' in options: verbose_flag = True else: verbose_flag = False if __name__ == "__main__": try: main() except Exception, e: print "ERROR, UNEXPECTED EXCEPTION" print str(e) traceback.print_exc() os._exit(1)
