这为什么报错，怎么网上教程这么写就没事

Question

import requests
from bs4 import BeautifulSoup
url = "https://www.umei.net/bizhitupian/meinvbizhi/yangyanmeinv.htm"
dicc = {"user-agent": "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/91.0.4472.114 Safari/537.36"}
a = requests.get(url, headers = dicc)
a.encoding = 'utf-8'
b = BeautifulSoup(a.text,'html.parser')
c = b.find("div", class_="Typelist").find_all("a")
print(c)

c = b.find("div", class_="Typelist").find_all("a")

AttributeError: 'NoneType' object has no attribute 'find_all'

更新：已解决，倒数第二行，c = b.find("div", class_="Typelist").find_all("a")

是TypeList 不是 Typelist

Answer 1

打印下 b.find("div", class_="Typelist")，应该是没有内容的，所以用.find_all("a")报错
