Hi,
I'm having some minor problems with optparse. I'm just worried that
someone shouldn't say that multiple argument feature isn't implemented
in optpartse.
How to tackle multiple arguments to an option ?
As far as I dug, I've found that >1 arguments are being ignored.
parser.add_opti on("", "--my-option", dest="my_option ", action="store",
type="string")
Now if someone uses it as:
../foo --my-option a b c
I want somehow to store all the three arguments but my_option stores
only "a" while ignoring b and c.
Any help?

I just noticed that the args variable is holding values b and c.
the args variables comes from:
(options, args) = parser.parse_ar gs()
I guess I only need to figure out now is why args isn't storing
argument "a" also...

I fixed it, I guess.
parser.add_opti on("", "--my-option", dest="my_option ",
action="store_t rue")
sets my_option to True and the arguments are all stored in the list
"args". :-)

note that whatever action you're using, args holds the *remaining* arguments, after
option processing.

It might do you good to read the documentation instead of blindly
experimenting.
Anyway,
parser.add_opti on("", "--my-option", nargs=3) http://docs.python.org/lib/optparse-...n-actions.html

That won't help because by design of my program, I can't limit the
number of arguments a user can pass to it.

do you want options, arguments, or are you just somewhat confused ?
</F>
I'm not sure about that.
My program will accept user input. The user can input multiple
arguments. maybe 1 or maybe 100, that's not definite. I do need option
because this particular (multiple) argument criteria is for one single
option.
Thanks,

Currently optparse doesn't support options with an arbitrary number of
arguments. I'm currently working on a optparse-inspired replacement
which does support this along the lines of:
parser.add_opti on('--my-option', nargs='*')
but it's not quite ready for prime-time yet. I'm hoping to put an
announcement out in the next couple of weeks.

Posted to the Optik list, but it seems defunct. Optik is now Python's
optparse.
I wonder how do you implement optional arguments to Optik. I.e., you
can have an option
-P
-- the filename is optional, with a default "data,pikl". It works as

Hi,
I would like to know your thoughts on a proposed change to optparse
that I have planned. It is possible to add default values to multiple
options using the set_defaults. However, when adding descriptions to
options the developer has to specify it in each add_option() call.
This results in unreadable code such as:
