optparse TypeError
in [Python]
|
From: dirknbr on 28 Jun 2010 09:30 I get an int object is not callable TypeError when I execute this. But I don't understand why. parser = optparse.OptionParser("usage: %lines [options] arg1") parser.add_option("-l", "--lines", dest="lines", default=10, type="int", help="number of lines") parser.add_option("-t", "--topbottom", dest="topbottom", default="T", type="str", help="T(op) or B(ottom)") (options, args) = parser.parse_args() if len(args) != 1: parser.error("incorrect number of arguments") lines=options.lines tb=options.topbottom Dirk lines(args[0],topbottom=tb,maxi=lines)

But 'lines' has been assigned an integer above. I'm assuming that elsewhere you've defined a function called 'lines'. You'll need to call either the function or the option by another name. -- Cheers, Simon B.

Use plac! $ cat x.py import plac @plac.annotations( lines=('number of lines', 'option', 'l', int), topbottom=('T(op) or B(ottom)', 'option', 't', str, 'TB')) def main(arg, lines=10, topbottom='T'): print arg, lines, topbottom if __name__ == '__main__': plac.call(main) $ python x.py -h usage: x.py [-h] [-l 10] [-t T] arg positional arguments: arg optional arguments: -h, --help show this help message and exit -l 10, --lines 10 number of lines -t T, --topbottom T T(op) or B(ottom) (see http://pypi.python.org/pypi/plac)

The OP should be made aware that: * plac is a third-party library with (TTBOMK) no prospect of inclusion in the standard library * optparse is in the standard library and has been for many versions * argparse is a third-party library that is now accepted for inclusion in the standard library, intended as a full optparse replacement <URL:http://www.python.org/dev/peps/pep-0389/> Choose accordingly. -- \ “If consumers even know there's a DRM, what it is, and how it | `\ works, we've already failed.” —Peter Lee, Disney corporation, | _o__) 2005 | Ben Finney

Both clog your scripts with wasted lines and your memory with complex interfaces far worse than colon clogging junk food can hold a candle to. Give your *script* an enema, and do *yourself* a favor by harnessing the simplistic elegance of the "optphart" module instead! #-- Start Script --# def optphart(args): d = {'args':[]} for arg in args: if arg.startswith('-'): key, value = arg.split('=', 1) options = value.split(',') if len(options) > 1: d[key[1:]] = options else: d[key[1:]] = [value] else: d['args'].append(arg) return d if __name__ == '__main__': args = [ 'nakedArgumentOne', 'nakedArgumentTwo', '-file=aSingleFile.txt', '-files=aFileOne.txt,aFileTwo.txt', '-options=Op1,Op2,Op3,Op4', '-help=this_is_some_unhelpful_help', ] opts = optphart(args) #print opts.keys() for k,v in opts.items(): print '%s -> %s' %(k, v) #-- End Script --# |
