python argument parser example

Example 1: python parse args

# parsing arguments with argparse is too easy
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))

Example 2: parser = argparse.ArgumentParser()

import argparse
parser = argparse.ArgumentParser()
parser.parse_args()
