Python - Argparse

Question

I've a file a.py . I want to write a command

python a.py create b c d e

which creates the b , c , d , and e ES index. How can I add b , c , d , and e into the commandline?

Following is my code:-

parser = argparse.ArgumentParser()
parser.add_argument("create", help="Creates index of the given app name.")
if args.create_index:
    pass

I get the following error:-

a.py: error: too few arguments

Answer 1

You can use the nargs parameter for your parser, like so

import argparse

parser = argparse.ArgumentParser()
parser.add_argument('indexes', type=str, nargs='+')

args = parser.parse_args()
print args.indexes

➜ python test.py a b c d e
['a', 'b', 'c', 'd', 'e']
