在你提供的代码中，你希望在下载音乐的过程中增加一个进度条来显示下载进度。为了实现这个目标，我们可以使用 `tqdm` 库来创建一个进度条。

首先，确保你已经安装了 `tqdm` 库。可以使用以下命令来安装：

pip install tqdm

接下来，我们需要对 `download_music` 函数进行修改，以添加进度条。请将以下代码替换到 `download_music` 函数中：

def download_music():
    ppp = ac.get(ac.curselection())
    pp = re.search('thread.*?htm', ppp)
    v = pp.group()
    url1 = 'https://www.hifini.com/' + v
    response = requests.get(url=url1, headers=headers)
    ppp = response.text
    l2 = re.search('<script>.*?title:..(.*?).,.*?author:.(.*?).,.*?url:..(.*?).,', ppp, flags=re.S)
    p = 'https://www.hifini.com/' + l2.group(3)
    response = requests.get(url=p, headers=headers, stream=True)  # 设置 stream=True 以启用流式下载
    total_size = int(response.headers.get('Content-Length'))
    music_name = '{}-{}.mp3'.format(l2.group(2), l2.group(1))
    progress_bar = tqdm(total=total_size, unit='B', unit_scale=True)  # 创建进度条
    with open(music_name, 'wb') as f:
        for data in response.iter_content(chunk_size=1024):
            progress_bar.update(len(data))  # 更新进度条
            f.write(data)
    progress_bar.close()  # 关闭进度条
    print(music_name)

在上面的代码中，我们首先通过 `response.headers.get('Content-Length')` 获取文件的总大小，然后使用 `tqdm(total=total_size, unit='B', unit_scale=True)` 创建一个进度条。在每次迭代下载数据时，我们使用 `progress_bar.update(len(data))` 来更新进度条，并将数据写入文件。

这样，当你点击下载按钮时，将会显示一个进度条来显示下载进度。记得先导入 `tqdm` 库和修改 `download_music` 函数，然后重新运行代码。希望能帮到你！
