<h2><img fetchpriority="high" decoding="async" class="alignnone size-full wp-image-1457" src="http://cdn.hyclive.cn/dixunblog/2026/03/生成-Python-爬虫入门实战图片.png" alt="" width="2730" height="1535" /></h2>
<h2>一、环境准备</h2>
<pre><code class="language-bash">pip install requests beautifulsoup4 lxml</code></pre>
<h2>二、基础请求</h2>
<pre><code class="language-python">import requests

# GET 请求
response = requests.get('https://www.example.com')
print(response.status_code)
print(response.text)</code></pre>
<h2>三、解析 HTML</h2>
<pre><code class="language-python">from bs4 import BeautifulSoup

html = '''</code></pre>
<h1>标题</h1>
<pre><code class="language-python"></code></pre>
<p>&#8221;&#8217; soup = BeautifulSoup(html, &#8216;lxml&#8217;) print(soup.h1.text)</p>
<pre><code class="language-python"></code></pre>
<h2>四、实战示例</h2>
<pre><code class="language-python"># 爬取新闻标题
import requests
from bs4 import BeautifulSoup

url = 'https://news.example.com'
response = requests.get(url)
soup = BeautifulSoup(response.text, 'lxml')

headlines = soup.find_all('h2', class_='headline')
for h in headlines:
    print(h.text)</code></pre>
<h2>五、注意事项</h2>
<ol>
<li>遵守 robots.txt 协议</li>
<li>控制请求频率</li>
<li>使用 User-Agent</li>
<li>合法合规使用数据</li>
</ol>
<h2>六、总结</h2>
<p>网络爬虫是 Python 实战的重要应用。建议多实践。</p>
