您希望使用索引來循環訪問 和 ，而不是列表大小inamesaddress
for i in range(num_page_items):
print(f"{names[i].text} : {address[i].text}")或者只是循環使用兩者zip
for name, ad in zip(names, address):
print(f"{name.text} : {ad.text}")

您正在嘗試訪問具有其長度的列表，而不是迭代器變量i
print(f"{names[num_page_items].text} : {address[num_page_items].text}")自
print(f"{names[i].text} : {address[i].text}")

你很接近。要從網頁 https://www.yell.com/ 中提取所有名稱和地址，您必須誘導WebDriverWait，并且可以使用以下任一定位器策略：visibility_of_all_elements_located()
代碼塊：
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：您必須添加以下導入：
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
