硒无效arg

Question

我开设了一门课，作为硒驱动器的基本设置。当我运行它时，我 收到一条错误消息，称为“无效参数”，我不该做。

我认为此代码中的元组“ url”存在错误。请帮助我。

SeleniumDriver类：     '''chromedriver（硒）的基本设置'''

def __init__(self, 
             driversource='C:\\Users\Ewis\Downloads\chromedriver.exe',
             url = ('https://realpython.com/')
             ):
    self.driversource = driversource
    self.url = url # this tuple

def __enter__(self):
    self.driver = webdriver.Chrome(executable_path=self.driversource)
    for urls in self.url:
        self.driver.get(urls)
    return self.driver, Keys

def __exit__(self, exc_type, exc_val, exc_trace):
    self.driver.quit()

回溯（最近通话最近一次）：

 File "<stdin>", line 1, in <module>
  File "c:\python\progs\my_modules\seleniumdriver\seleniumdriver.py", line 16, in __enter__
    resp = self.driver.get(urls)
  File "C:\python\python run 3.7.3\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 333, in get
    self.execute(Command.GET, {'url': url})
  File "C:\python\python run 3.7.3\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 321, in execute
    self.error_handler.check_response(response)
  File "C:\python\python run 3.7.3\lib\site-packages\selenium\webdriver\remote\errorhandler.py", line 242, in check_response
    raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.InvalidArgumentException: Message: invalid argument
  (Session info: chrome=75.0.3770.100)

欢迎使用Stackoverflow。可能的错误是您没有将元组作为url参数传递。正确的格式是

    def __init__(self, 
                 driversource='C:\\Users\Ewis\Downloads\chromedriver.exe',
                 url = ('https://realpython.com/', )
                 ):
        self.driversource = driversource
        self.url = url # this tuple

在没有几乎不引人注意的逗号的情况下，您的默认url参数很简单 带括号的字符串。
