python爬取微博想要的评论

要爬取微博的评论，可以使用Python中的第三方库进行实现。常用的库有requests、BeautifulSoup、selenium等。下面是一个简单的示例代码，来实现爬取指定微博的评论：

import requests
from bs4 import BeautifulSoup

# 定义要爬取的微博链接和评论页数
weibo_url = 'https://weibo.com/1234567890/ABCDEFGHI?type=comment'
page_count = 3

# 模拟请求头，加上User-Agent信息
headers = {
    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3'}

# 发送请求，获取页面内容
response = requests.get(weibo_url, headers=headers)
html = response.text

# 使用BeautifulSoup解析页面
soup = BeautifulSoup(html, 'html.parser')

# 定位评论所在div标签
comment_divs = soup.find_all('div', class_='list_li S_line1 clearfix')

# 遍历每个评论div，提取评论内容
comments = []
for comment_div in comment_divs:
    comment = comment_div.find('span', class_='ctt').text.strip()
    comments.append(comment)

# 打印评论内容
for i, comment in enumerate(comments):
    print(f'评论{i+1}: {comment}')

上述代码中，需要替换weibo_url为要爬取的微博链接，page_count为要爬取的评论页数。运行代码后，就可以获取到微博的评论内容。<span class="em">1</span>
