I’ve been using argparse
for a Python program that can -process
, -upload
or both:
parser = argparse.ArgumentParser(description='Log archiver arguments.') parser.add_argument('-process', action='store_true') parser.add_argument('-upload', action='store_true') args = parser.parse_args()
The program is meaningless without at least one parameter. How can I configure argparse
to force at least one parameter to be chosen?
UPDATE:
Following the comments: What’s the Pythonic way to parametrize a program with at least one option?

Answer
if not (args.process or args.upload): parser.error('No action requested, add -process or -upload')
