Use argparse for command-line arguments

[magsol]

Finish filling out the command-line arguments in terms of the argparse package in Python.

First of all sorry because I'm a beginner in python, actually I've wrote the following code but I dont know why there is some error , I think I should recall the values from somewhere but I need some help:

import argparse import sys

def main():

parser = argparse.ArgumentParser(description='close bug')

parser = argparse.ArgumentParser(description = 'PySpark Dictionary Learning',
    add_help = 'How to use', prog = 'python code1.py <args>')
parser.add_argument("-i", "--input", required = True,
    help = "Input File name.")
parser.add_argument("-d", "--dictionary", required = True,
    help = "Dictionary File name.")
parser.add_argument("-o", "--output", required = True,
    help = "Output File name.")
parser.add_argument("-s", "--summary", required = True,
    help = "Summary File name.")
parser.add_argument("-l", "--length", type = int, required = True,
    help = "Length of the samples.")
parser.add_argument("-P", "--pnumeber", type = int, required = True,
    help = "Number of the samples.")
parser.add_argument("-m", "--mDicatom", type = int, required = True,
    help = "Number of the dictionary atoms.")
parser.add_argument("-e", "--epsilon", type = float, required = True,
    help = "The value of epsilon.")

args = vars(parser.parse_args())

print(args['input'])
print(args['dictionary'])
print(args['output'])
print(args['summary'])

if name == "main": main()

What is the error message?

The following message is appeared is console( by the way I'm using Python 3.5 and Sublime Text 3) :

usage: python code1.py [-h] -i INPUT -d DICTIONARY -o OUTPUT -s SUMMARY -l LENGTH -P PNUMEBER -m MDICATOM -e EPSILON python code1.py : error: the following arguments are required: -i/--input, -d/--dictionary, -o/--output, -s/--summary, -l/--length, -P/--pnumeber, -m/--mDicatom, -e/--epsilon [Finished in 0.2s with exit code 2]

Read the error message: "the following arguments are required." It's not running because you specified the arguments as required in the Python code, but didn't feed them in when you ran the program.

yeah Thanks, but how should I feed them during running ? I mean through a function or ?

[magsol]

python scriptname.py -opt1 arg1 -opt2 arg2

And so forth.
