Greetings, The usual way of resolving configuration is command line -> environment -> default. Currently argparse supports only command line -> default, I'd like to suggest an optional "env" keyword to add_argument that will also resolve from environment. (And also optional env dictionary to the ArgumentParser __init__ method [or to parse_args], which will default to os.environ). Example: [spam.py]
from os import environ as env
parser = ArgumentParser() parser.add_argument('--spam', env='SPAM', default=7)
parser.add_argument('--spam', default = env.get('SPAM', 7))
This is about the same number of chars to type and I believe it is available now in all versions. I like it better because it puts the e.v. name and default right together.
