New submission from fralau <laur2...@yahoo.co.uk>:
With argparse, an common requirement is is that a user may want to pass a series of key/value pairs (a sort of equivalent of **args on the command line). Here is a solution that could be implemented in the standard library with little effort. This can be done so, e.g.: command --set foo=hello bar="hello world" baz=5 With the benefit of experience, this is easy and very intuitive. This does not require any modification, as the '--set' option can be defined as: nargs='+', metavar="KEY=VALUE" The next step is to parse the resulting list. See github gist for a trivial implementation: https://gist.github.com/fralau/061a4f6c13251367ef1d9a9a99fb3e8d). It might be useful to integrate a helper method to the standard library together with an explanation in the doc on how to do it. ---------- components: Library (Lib) messages: 324043 nosy: fralau priority: normal severity: normal status: open title: Argparse library: parse --set type type: enhancement _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue34496> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
