python - 为什么找不到元素 'a' ？

Question

获取“div”元素，但以同样的方式获取“a”元素。

import requests
from bs4 import BeautifulSoup as bf

# link :
url = "https://www.imdb.com/search/name/?gender=male,female&ref_=nv_tp_cel"


Response = requests.get(url)

soup = bf(Response.text,'lxml')

div = soup.find_all('div', class_ = "lister-item-content")


a_tag = div.find_all('a')

print(a_tag)

我想打印“div”元素中的所有“a”元素。

Answer 1

迭代每个 div 元素，然后使用 div.findChildren 迭代每个 a 子元素:

import requests
from bs4 import BeautifulSoup as bf

# link :
url = "https://www.imdb.com/search/name/?gender=male,female&ref_=nv_tp_cel"


Response = requests.get(url)

soup = bf(Response.text,'lxml')

divs = soup.find_all('div', class_ = "lister-item-content")

for div in divs:
    a_tags = div.findChildren('a')

    for a_tag in a_tags:
        print (a_tag)

这会打印出类似的内容:
