python 爬网站清单

Python 是一种强大的编程语言，它的爬虫功能非常出色。使用 Python，可以轻松地爬取各种网站上的数据。下面是一份 Python 爬取网站清单。

1. 爬取网页：requests, urllib
import requests
response = requests.get('https://www.example.com')
html = response.text
2. 解析 HTML：BeautifulSoup
from bs4 import BeautifulSoup
soup = BeautifulSoup(html, 'html.parser')
title = soup.title.string
3. 获得元素：XPath, CSS Selector
title = soup.select('title')[0].text
paragraphs = soup.xpath('//p/text()')
4. 爬取图片：requests, Pillow
import requests
from PIL import Image
from io import BytesIO
response = requests.get('https://www.example.com/image.png')
img = Image.open(BytesIO(response.content))
5. 爬取 JSON 数据：requests
import requests
response = requests.get('https://www.example.com/data.json')
json_data = response.json()
6. 爬取 XML 数据：xml.etree.ElementTree
import xml.etree.ElementTree as ET
response = requests.get('https://www.example.com/data.xml')
xml_data = response.content
root = ET.fromstring(xml_data)

Python 爬取网站的利用非常广泛。上面的清单只是其中的一部份。通过学习这些爬虫技能，你可以开始用 Python 获得你需要的数据。
