Question

从网络抓取数据时遇到问题

以下提到我曾尝试过

import requests
from bs4 import BeautifulSoup


# Collect and parse first page
page = requests.get('https://www.jiosaavn.com/album/vijayashanti-birthday-telugu-hits/A05RmafpUiI_')
soup = BeautifulSoup(page.text, 'html.parser')

# Pull all text from the BodyText div
artist_name_list = soup.find(class_='song-wrap')

# Pull text from all instances of <a> tag within BodyText div
artist_name_list_items = artist_name_list.find_all('a')

for artist_name in artist_name_list_items:
    print(artist_name.prettify())

我除了正确的输出

Answer 1

find如果找不到合适的元素，则返回None。您需要先检查其返回值，然后再尝试在其上调用find_all：

# Pull all text from the BodyText div
artist_name_list = soup.find(class_='song-wrap')

# Check that a song-wrap item was found
if artist_name_list:

    # Pull text from all instances of <a> tag within BodyText div
    artist_name_list_items = artist_name_list.find_all('a')

    for artist_name in artist_name_list_items:
        print(artist_name.prettify())

AttributeError：'NoneType'对象没有属性'find_all'吗？
