I'm trying to pass arguments in a Flask application with argparse:

app = Flask(__name__)

parser = argparse.ArgumentParser()
parser.add_argument("-e", "--environ", dest='environ', default='production',
                    help="Server environment")
args = parser.parse_args()

if args.environ == 'dev':
    app.config.from_pyfile("dev.cfg", silent=True)
else:
    app.config.from_pyfile("product.cfg", silent=True)

Everything is OK when I run the script directly. However I don't know how to pass "-e dev" argument in uwsgi config file, pyargv cannot handle this kind of argument.

    pyargv simply populate the sys.argv list. So you can use it as argparse (as all of the pther arg parsers) read that list – roberto Nov 16 '14 at 05:25
  • You're right! I use positional argument instead of keyword argument and uwsgi works fine now. And I still want to know there is any way to pass keyword argument in uwsgi. – Vayn Nov 16 '14 at 08:43

    there is no such thing as keyword arguments. The system passes arguments as a dumb array that the python engine maps to sys.argv list. argparse only parses this list by conventions. --payargv "-e foobar" is perfectly valid. – roberto Nov 16 '14 at 09:25
  • You can use `pyargv=-e dev` in a .ini file. See my answer at https://stackoverflow.com/a/46702137/1410035 for more detail – Tom Saleeba Oct 12 '17 at 05:38

You can use this code:

parser.add_argument("-e", "--environ", dest='environ', default='production', help="Server environment", required=False)
