让Selenium对多个URL执行相同的过程

Question

I created a script that goes to a property auction site that monitors the price and alerts me of any of the changes. I originally made it to monitor 1 url at a time. I now need it to monitor more then 1 url and do the same exact process at the same time.

I've tried looping the urls in browser.get but that doesn't seem to work for me(idk if i wrote it wrong, probably did). But i need it to either, open a tun of new tabs and go to the urls, or another way for it to monitor everything.

The Original Script for 1 property url, works perfectly, And the only difference between that and the code below is browser.get .

PS: If script is run, and auction urls are expired (meaning theres no price it can look at) there will be a error

Your code seems to be mostly fine and cycles through them for me. Unfortunately all the properties are not for sale, so they all give me errors and I cannot produce the expected behaviour. I think you should implement a try: and except: , the finally: runs regardless of what happened, and I wouldn't imagine you want an update every 2 seconds XD. You also don't need continue at the end, it does nothing. The code

browser = webdriver.Chrome()

# Start URL switch tryouts.

while True:
    for url in urls:
        browser.get(url)

        # This is the process i need all urls to do.
        time.sleep(2)
        address = soup(browser.page_source, 'html.parser').find('span', {'class': 'h1'}).text
        try:
            propertyprice = browser.find_element_by_css_selector('span.current-bid')
            currentBidText = propertyprice.text
            WebDriverWait(browser, 90000).until(
                EC.text_to_be_present_in_element((By.CSS_SELECTOR, 'span.current-bid'), currentBidText)
                )
        except Exception as e:
            print("an error occurred on property {}:\n{}".format(address.strip(), e))
        finally:
            pass
            # print("+++ Send notifications.")
            # account_sid = "***"
            # auth_token = "***"
            # client = Client(account_sid, auth_token)

            # print("+ Send notifications to: ", PhoneNumber1, " and ", PhoneNumber2)
            #
            # sendTo1 = "{\"binding_type\":\"sms\",\"address\":\"" + PhoneNumber1 + "\"}"
            # print("+ sendTo1: ", sendTo1)
            # sendTo2 = "{\"binding_type\":\"sms\",\"address\":\"" + PhoneNumber2 + "\"}"
            # print("+ sendTo2: ", sendTo2)
            #
            # notify_service_sid = "***"
            # notification = client.notify.services(notify_service_sid).notifications.create(
            #         body='There has been a change at: '+address,
            #         to_binding=[sendTo1, sendTo2]
            #     )
            #
            # print("+ Notification SID: ", notification.sid)
            #
            # print("+++ Exit.")

Does cycle through all the properties, and a sample output for me is:
