python argparse parse_args code 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: how to use argparse

import argparse

if __name__ == "__main__":
	#add a description
	parser = argparse.ArgumentParser(description="what the program does")

	#add the arguments
	parser.add_argument("arg1", help="advice on arg")
	parser.add_argument("arg2", help="advice on arg")
#						.
# 						.
#   					.
	parser.add_argument("argn", help="advice on arg")

	#this allows you to access the arguments via the object args
	args = parser.parse_args()

	#how to use the arguments
	args.arg1, args.arg2 ... args.argn
