optparse

[Torsten Mohr]

Hi,

i use the module optparse to parse the command line:

------example
#! /usr/bin/python

import optparse

parser = optparse.OptionParser()

parser.add_option("-v", "--verbose",
dest = 'verb',
help = 'be loud',
action = 'store_true',
default = 'store_false')

(opts, args) = parser.parse_args()

print "opts", opts
print "args", args
------example

If i call it without any parameters i get:

opts {'verb': 'store_false'}
args []


I would rather like to see the actual value False in "opts",
did i use some wrong parameters somewhere? I can't imagine
that this is the wanted behaviour of optparse.


Thanks for any hints,
Torsten.

Hi,

If i call it without any parameters i get:

opts {'verb': 'store_false'}
args []

If i call it with parameter -v i get:

../script.py -v

opts {'verb': True}
args []


I wonder what's wrong here.


Best regards,
Torsten.

if you want `False` as default you should actually use `False` and not
the string 'store_false'.

I'm assuming you read at least some of the docs. This page makes it
pretty clear:
