這是我的整個代碼。response = requests.get("https://www.zomato.com/san-francisco/restaurants?q=restaurants&page=" + str(i),headers=headers)content = response.contentbs = BeautifulSoup(content, "html.parser")zomato_containers = bs.find_all("div", {"class": "search-snippet-card"})for zomato_container in zomato_containers: title = zomato_container.find("a", {"class": "result-title"}).get_text() numVotes = zomato_container.select_one('[class^=rating-votes-div]').text numVotes = numVotes[1] if len(numVotes) > 1 else numVotes[0] print("restaurant_title: ", title) print("numVotes: ", numVotes)我收到一個錯誤：“numVotes = zomato_container.select_one('[class^=rating-votes-div]').text AttributeError: 'NoneType' 對象沒有屬性 'text'”我非?？隙ㄟ@是因為頁面上的某些元素不存在。我試圖跳過這些元素，但無法弄清楚如何。非常感謝。我非常感激。

最簡單的方法是：
for zomato_container in zomato_containers:
title = zomato_container.find("a", {"class": "result-title"}).get_text()
try:
numVotes = zomato_container.select_one('[class^=rating-votes-div]').text
numVotes = numVotes[1] if len(numVotes) > 1 else numVotes[0]
except AttributeError:
continue
print("restaurant_title: ", title)
print("numVotes: ", numVotes)

您可以在嘗試訪問text屬性之前測試變量是否為 None
import requests
from bs4 import BeautifulSoup as bs
i = 1
headers = {'User-Agent': 'Mozilla/5.0'}
response = requests.get("https://www.zomato.com/san-francisco/restaurants?q=restaurants&page=" + str(i),headers=headers)
content = response.content
soup = bs(content, "html.parser")
zomato_containers = soup.select('.search-snippet-card')
for zomato_container in zomato_containers:
title = zomato_container.find("a", {"class": "result-title"}).get_text()
numVotes = zomato_container.select_one('[class^=rating-votes-div]')
if numVotes is None:
numVotes = 'N/A'
else:
numVotes = numVotes.text.strip()
print("restaurant_title: ", title)
print("numVotes: ", numVotes)
