Python爬取知乎网站代码

Python爬取知乎网站通常涉及网络请求库如`requests`和解析HTML内容的库如`BeautifulSoup`或`lxml`。以下是一个简单的示例，展示如何用Python爬取知乎文章标题：

import requests
from bs4 import BeautifulSoup

# 定义目标URL
url = "https://www.zhihu.com/topic/19550876/top-answers"

# 发送GET请求获取网页内容
response = requests.get(url)

# 检查请求是否成功
if response.status_code == 200:
    # 解析HTML
    soup = BeautifulSoup(response.text, 'html.parser')
    
    # 找到包含文章标题的部分（这里假设是h2标签）
    article_titles = soup.find_all('h2', class_='QuestionItem-title')

    for title in article_titles:
        print(title.get_text())  # 输出文章标题
else:
    print("请求失败，状态码:", response.status_code)
