Python 索引器错误：迭代两个webelements列表时，列表索引超出范围

我试图在终端上打印结果，但收到以下错误消息：

IndexError: list index out of range

下面是代码，提前感谢您的帮助。 这个领域真正的初学者

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

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()

您希望使用索引

i

来迭代

名称

和

地址

，而不是列表大小

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

或者只需使用

zip在两者上循环

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

您正在尝试使用列表的长度而不是迭代器变量
i

print(f"{names[num_page_items].text} : {address[num_page_items].text}")

到

你很接近。要从网页中提取所有名称和地址，您必须诱导WebDriverWait以查看所有元素的可见性（）

，并且您可以使用以下任一项：

• 代码块：

  names = [my_elem.text for my_elem in WebDriverWait(driver, 10).until(EC.visibility_of_all_elements_located((By.CSS_SELECTOR, "span.businessCapsule--name")))]
  address = [my_elem.text for my_elem in WebDriverWait(driver, 10).until(EC.visibility_of_all_elements_located((By.CSS_SELECTOR, "a.businessCapsule--address")))]
  for i,j in zip(names, address):
      print("{} address is {}".format(i, j))
  

• 注意：您必须添加以下导入：

  from selenium.webdriver.support.ui import WebDriverWait
  from selenium.webdriver.common.by import By
  from selenium.webdriver.support import expected_conditions as EC
