python实例豆瓣音乐代码_Python使用Beautiful Soup爬取豆瓣音乐排行榜过程解析

好的，以下是使用Python和Beautiful Soup爬取豆瓣音乐排行榜的代码和过程解析：

1. 导入所需的库

import requests
from bs4 import BeautifulSoup

2. 通过requests库向网站发送请求，获取网页内容

url = 'https://music.douban.com/chart'
headers = {'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3'}
response = requests.get(url, headers=headers)
html = response.text

3. 使用Beautiful Soup解析网页内容

soup = BeautifulSoup(html, 'html.parser')

4. 定位需要爬取的信息

豆瓣音乐排行榜中包含歌曲的排名、歌曲名称、歌手和评分等信息，我们需要定位到这些信息所在的HTML标签和类名。

songs = soup.find_all('tr', class_='item')

5. 提取信息并进行存储

for song in songs:
    rank = song.find('span', class_='ranking_num').get_text().strip()
    title = song.find('a', class_='nbg').get_text().strip()
    artist = song.find('p', class_='pl').get_text().strip()
    rating = song.find('span', class_='rating_nums').get_text().strip()
    print(rank, title, artist, rating)

完整代码如下：

import requests
from bs4 import BeautifulSoup

url = 'https://music.douban.com/chart'
headers = {'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3'}
response = requests.get(url, headers=headers)
html = response.text

soup = BeautifulSoup(html, 'html.parser')

songs = soup.find_all('tr', class_='item')

for song in songs:
    rank = song.find('span', class_='ranking_num').get_text().strip()
    title = song.find('a', class_='nbg').get_text().strip()
    artist = song.find('p', class_='pl').get_text().strip()
    rating = song.find('span', class_='rating_nums').get_text().strip()
    print(rank, title, artist, rating)

此代码可爬取豆瓣音乐排行榜前100首歌曲的信息。
