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()
