第1关：文本提取入门 ⭐

💡 提示

使用 BeautifulSoup 的 find() 和 find_all() 方法

示例代码：

from bs4 import BeautifulSoup
import requests

url = 'https://req.haleibc.com/level1'
response = requests.get(url)
soup = BeautifulSoup(response.text, 'html.parser')

# 提取标题
title = soup.find('h2', class_='main-title').text
print(title)

# 提取所有段落
paragraphs = soup.find_all('p', class_='content')
for p in paragraphs:
    print(p.text)
