在Python中，有許多強大的爬蟲庫可以幫助您抓取數據。以下是一些常用的庫及其使用方法：
pip install requests示例代碼：
import requests
url = 'https://example.com'
response = requests.get(url)
content = response.text
pip install beautifulsoup4示例代碼：
from bs4 import BeautifulSoup
html = '''
<html>
<head>
<title>Example</title>
</head>
<body>
<h1>Hello, World!</h1>
<p class="content">Some content here.</p>
</body>
</html>
'''
soup = BeautifulSoup(html, 'html.parser')
title = soup.title.string
paragraph = soup.find('p', class_='content').string
pip install scrapy示例代碼：
import scrapy
class ExampleSpider(scrapy.Spider):
name = 'example'
start_urls = ['https://example.com']
def parse(self, response):
self.log('Visited %s' % response.url)
title = response.css('title::text').get()
paragraph = response.css('p.content::text').get()
yield {'title': title, 'paragraph': paragraph}
pip install selenium示例代碼：
from selenium import webdriver
url = 'https://example.com'
driver = webdriver.Chrome()
driver.get(url)
title = driver.find_element_by_tag_name('title').text
paragraph = driver.find_element_by_css_selector('p.content').text
driver.quit()
這些庫可以單獨使用，也可以結合使用以滿足不同的抓取需求。在使用爬蟲時，請確保遵守目標網站的robots.txt規則，并尊重網站的版權和隱私政策。
