AttributeError：'ArgumentParser'对象没有属性'parse_arg'

Question

当我将cli参数传递为：'python auto_refresh.py -web_address https://stackoverflow.com/']时，出现此错误>

错误显示为：

Traceback (most recent call last):
  File "auto_refresh.py", line 14, in <module>
    option=get_arguments()
  File "auto_refresh.py", line 8, in get_arguments
    option = args.parse_arg()
    AttributeError: 'ArgumentParser' object has no attribute 'parse_arg'
'''

import time
from selenium import webdriver
import argparse

def get_arguments():
    args = argparse.ArgumentParser()
    args.add_argument("-w","-- web_address",dest="web_address",help= "enter web_address")
    option = args.parse_arg()

     if not option.web_address:
        parser.error("[-] please specify web address, use --help for more info")
     else :
        return args

option=get_arguments()

    driver= webdriver.Chrome()
    driver.get(option.web_address)

    while true:

        time.sleep(3)
        driver.refresh()
        time.sleep(2)
        driver.close()

在此脚本中运行并传递cli参数的可行解决方案是什么？有什么帮助吗？
