There is a simple solution in Python 3.6 if you're simply trying to convert argparse input to a dictionary. An example is as follows:

import argparse 

parser = argparse.ArgumentParser()
parser.add_argument('-i', '--input', help='the path to the input file')
parser.add_argument('-o', '--output', help='the path to the output file')
args = parser.parse_args()

arguments = dict(args._get_kwargs())

for k, v in arguments.items():
    print(k, v) 

Given command line input such as python3 script_name.py --input 'input.txt' --output 'output.txt' the code would output to terminal:

input input.txt
output output.txt
