以下是代码，在此先感谢您的帮助.这个领域的真正初学者.

Below is the code, thanks in advance for your help. Truly beginner to this field.

import pandas as pd
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
import time

option = Options()
option.add_argument("--disable-infobars")
option.add_argument("start-maximized")
option.add_argument("--disable-extensions")
option.add_experimental_option("excludeSwitches", ['enable-automation'])

# Pass the argument 1 to allow and 2 to block
option.add_experimental_option("prefs", { 
    "profile.default_content_setting_values.notifications": 1 
})
driver = webdriver.Chrome(chrome_options=option, executable_path='C:\\Users\\Sheik\\Desktop\\web crawling\\chromedriver.exe')

driver.implicitly_wait(5000)

url = "https://www.yell.com/"

driver.get(url)

search_query_path = driver.find_element_by_xpath('''//*[@id="search_keyword"]''')
search_query_path.click()
search_query_path.send_keys("Garage Services")
search_city_path = driver.find_element_by_xpath('''//*[@id="search_location"]''')
search_city_path.click()
search_city_path.send_keys("London")
search_btn = driver.find_element_by_xpath('''//*[@id="searchBoxForm"]/fieldset/div[1]/div[3]/button''')
search_btn.click()


names = driver.find_elements_by_class_name("businessCapsule--name")
address = driver.find_elements_by_class_name("businessCapsule--address")

num_page_items = len(names)
for i in range(num_page_items):
    print(f"{names[num_page_items].text} : {address[num_page_items].text}")

driver.close()

推荐答案

您想使用索引 i 来迭代 names 和 address>，不是列表大小

You want to use the index i to iterate over names and address, not the list size

for i in range(num_page_items):
    print(f"{names[i].text} : {address[i].text}")

或者只是用 zip

for name, ad in zip(names, address):
    print(f"{name.text} : {ad.text}")
