如何在argparse python中實現* args和** kwargs

Question

這是我的代碼

import argparse

parser = argparse.ArgumentParser()

parser.add_argument("required_arg", metavar="username:pass@hostname")
parser.add_argument("--optional_arg", 
                    help="This optional argument should have args and 
                          kwargs implemented in it as I want to make 
                          it flexible eg.
                          it may have optional_arg1, 
                          optional_arg2, key1=value1, key2=value2 or 
                          it may have optional_arg1, key1=value1, 
                          key2=value2, key3=value3")

誰能在這個add_argument（）部分中向我展示實現* args和** kwargs的方法嗎？

我想您可能想看看做這樣的事情：

parser = argparse.ArgumentParser()
subparsers = parser.add_subparsers(dest='subparser')
