一、打开网页https://music.163.com/，进入榜单（热歌榜）

二、右键检查、刷新网页，选择元素（点击歌曲名）

三、相关代码

import requests
#正则表达式模块内置模块
import re
import os

filename = 'music\\'
if not os.path.exists(filename):
    os.mkdir(filename)
#如果想要爬取其他榜单的内容，只需要更改请求URL中的ID
url = 'https://music.163.com/discover/toplist?id=3778678'
#请求头
headers = {
        'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) '
                      'AppleWebKit/537.36 (KHTML, like Gecko) Chrome/107.0.0.0 Safari/537.36'
}
response = requests.get(url=url,headers=headers)
# print(response.text)
html_data = re.findall('<li><a href="/song\?id=(\d+)">(.*?)</a>',response.text)

for num_id,title in html_data:
    music_url = f'http://music.163.com/song/media/outer/url?id={num_id}.mp3'
    #对于音乐播放地址发送请求，获取二进制数据内容
    music_content = requests.get(url=url,headers=headers).content
    with open(filename + title +'.mp3',mode='wb') as f:
        f.write(music_content)
    print(num_id,title)

四、爬取结果
