这段代码有问题吗？ （Python爬行）

Question

I don't know why there is an error:

TypeError: list indices must be integers or slices, not str

This URL is a Korean question website.

import requests

from bs4 import BeautifulSoup

url = "http://www.algotank.com/bbs/board.php?bo_table=algotank&wr_id=16"

source = requests.get(url).text
soup = BeautifulSoup(source, 'html.parser')
AnsInput = soup.find_all("input",{"name":"AnsInput"})['answer']

print(AnsInput)

Answer 1

BeautifulSoup 的find_all将返回一个列表，而不是一个字典，所以如果你想要一个特定的元素，需要使用一个整数来索引，例如

AnsInput = soup.find_all("input",{"name":"AnsInput"})[0]['answer']
