爬取网站：https://www.9ku.com/

下载音乐代码：

import re
import os
import time
import requests
import urllib.parse

headers = {
    'Referer': 'https://www.9ku.com/',
    'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (Khtml, like Gecko) Chrome/91.0.4472.114 Safari/537.36'
}


def start_music():
    while True:
        name = input('请输入你要下载的歌曲名称：')
        name1 = urllib.parse.quote(name)
        url = f"https://baidu.9ku.com/song/?key={name1}"
        try:
            rep1 = requests.get(url=url, headers=headers).text
            dowm_url = 'https:' + re.search(r'<a target="_blank" href="(?P<d_url>.*?)" class="down">下载</a>',
                                            rep1).group('d_url')
            rep2 = requests.get(url=dowm_url, headers=headers).text
            return rep2
        except:
            print('没有找到，请输入正确的歌曲名称')
            continue


def music_down(resp):
    tag_music = re.search(r'<a href="(?P<d2_url>.*?)" style="display:none">(?P<mus_name>.*?)Mp3下载</a>', resp)
    music_url = tag_music.group('d2_url')
    music_name = tag_music.group('mus_name')
    print(music_url, music_name)
    if not os.path.exists('music'):
        os.mkdir('music')
    path = 'music/' + music_name + ".mp3"
    resp = requests.get(url=music_url, headers=headers).content
    with open(path, "wb") as f:
        f.write(resp)
        print(music_name, "下载完成")


def main():
    start = time.time()
    resp = start_music()
    music_down(resp)
    print("一共耗时", time.time() - start)


if __name__ == '__main__':
    main()

执行结果如下图：
