Best Way to Parse Python sys.argv

2013-09-30

import sys

import collections

arg_names =['command','x','y','operation','option']

args = dict(zip(arg_names, sys.argv))

print(args)

Arg_list = collections.namedtuple('Arg_list', arg_names)

args = Arg_list(*(args.get(arg,None)for arg in arg_names))

print(args)

print(args.command)

# if you need something more robust use argparse

import argparse

parser = argparse.ArgumentParser(description='Process some integers.')

parser.add_argument('integers', metavar='N', type=int, nargs='+',

help='an integer for the accumulator')

parser.add_argument('--sum', dest='accumulate', action='store_const',

const=sum, default=max,

help='sum the integers (default: find the max)')

args = parser.parse_args()

print args.accumulate(args.integers)
