如何在类中调用在类外部定义的函数

Question

我有一个属于类的网络爬虫：

class Request:
    logger = logging.getLogger('django.project.requests')
    selenium_retries = 0

    def __init__(self,url):
        self.url = url


    def run_sel(self,class_name):
        try:
            software_names = [SoftwareName.CHROME.value]
            operating_systems = [OperatingSystem.WINDOWS.value, OperatingSystem.LINUX.value]
            user_agent_rotator = UserAgent(sofware_names=software_names,operating_systems=operating_systems,limit=100)

            # set chrome_options
            chrome_options = Options()
            chrome_options.add_argument("--headless")
            chrome_options.add_argument("--no-sandbox")

            chrome_path = chromedriver_path()

            driver = webdriver.Chrome(executable_path=chrome_path, chrome_options=chrome_options)

            # get the site
            driver.get(self.url)

            time_to_wait = 90

            try:
                WebDriverWait(driver, time_to_wait).until(
                EC.presence_of_element_located((By.CLASS_NAME,class_name)))
            finally:

                driver.maximize_window()

                # scroll to the bottom

                old_position = 0
                new_position = None

                while new_position != old_position:
                    # Get old scroll position
                    old_position = driver.execute_script(
                        ("return (window.pageYOffset !== undefined) ?"
                        " window.pageYOffset : (document.documentElement ||"
                        " document.body.parentNode || document.body);"))
                    # Sleep and Scroll
                    time.sleep(1)
                    driver.execute_script((
                        "var scrollingElement = (document.scrollingElement ||"
                        " document.body);scrollingElement.scrollTop ="
                        " scrollingElement.scrollHeight;"))
                    # Get new position
                    new_position = driver.execute_script(
                        ("return (window.pageYOffset !== undefined) ?"
                        " window.pageYOffset : (document.documentElement ||"
                        " document.body.parentNode || document.body);"))

                # construct dictionary --- {link: , name: , fields: }

                # save individual's links
                elements = driver.find_elements_by_css_selector('a._32mo')
                contents = driver.find_elements_by_css_selector('div._pac')

                link = []
                name = []
                field = []

                for i in elements:
                    link.append(i.get_attribute('href'))
                    name.append(i.get_attribute('text'))

                for e in contents:
                    field.append(e.text)


                # create dictionary with three lists
                output = [{'scraped_name': name, 'link': link, 'text_string': field} for name, link, field in zip(name, link, field)]


                driver.close()

                # update_ind_scrape_status(i,ts,row_id)

                return output

        except (TimeoutException, WebDriverException):
            # self.logger.error(traceback.format_exc())
            time.sleep(6)
            # self.selenium_retries += 1
            # self.logger.info('Selenium retry # ' + str(selenium_retries))
            return self.run_sel(class_name)

我在类外定义了另一个函数，该函数将抓取状态推送到Google大查询：

def update_scrape_status(i,ts,s):
 # pushes scrape status to google big query table
# parameters:
i : scraped successfully, 1 or 0
ts : timestamp scraped
s : the string parameter that is pushed

我的问题是，如何将该函数嵌入到Request类中？另外，我需要在run_sel之前的driver.close()下运行它，但是我有点困惑，因为s中的update_scrape_status参数是由Request类之外的函数定义的。我是否也应该将它们嵌入到Request类中？

参数s定义为：

s = read_joined_table()[0]['string_name']


def read_joined_table():
 # function that calls a sample data from google big query

我对OOP不太熟悉，但是我想将scrape status函数嵌入到此类中，而不是将类更改为函数。
