Argparse“ArgumentError: argument -h/--help: conflicting option string(s): -h, --help”

Question

Recently, I am learning argparse module, Argument error occurred below the code

import argparse
import sys


class ExecuteShell(object):
    def create(self, arg         


        

Answer 1

The same error pop-ups in 2 other scenarios:

1) Repeated code

parser.add_argument('-h',
                        '--help',
                        action='store_true',
                        help=argparse.SUPPRESS)

parser.add_argument('-h',
                        '--help',
                        action='store_true',
                        help=argparse.SUPPRESS)

2) When you execute the code multiple times on the same kernel

I'm leaving it just in case if someone had simillar problem.
