构建一个 python argparser，它从 python 脚本代码中实现的列表中获取 arguments

Question

I am trying to develop a python script that instead of adding fix arguments, it will take the supported arguments from a list that is previously defined and filled with values parsed from an xml file. So that for instance - in the code example below, when passing test2.py -h it will display me the supported variables from that list. Later on each option from the list will have a relevant function to perform. (I've pre-defined the list in the example for simplification)

Is this supported by Python? Any ideas how this can be implemented?

import argparse
list = ['option1', 'option2', 'option3', 'option4', 'option5']
def arg_parser():
    '''setup argument parser'''
    parser = argparse.ArgumentParser()
    parser = argparse.ArgumentParser(description='Display data relevant to the option chosen')
    parser.add_argument(f"{list}", type=str, help='Choose one of the supported options')

    args = parser.parse_args()
    return args

arg_parser()
