可以使用开源的 Python 包 pyaudio 和 requests，通过获取并解码音频数据，实现从流媒体URL播放音频的效果。代码示例如下：

import pyaudio
import requests

CHUNK = 1024

def play_audio_stream(url):
    response = requests.get(url, stream=True)

    p = pyaudio.PyAudio()
    stream = p.open(format=pyaudio.paInt16, channels=1, rate=44100, output=True)

    # 从 URL 中获取音频数据并播放
    for data in response.iter_content(CHUNK):
        stream.write(data)

    stream.stop_stream()
    stream.close()
    p.terminate()

url = "https://example.com/audio.mp3"  # 实时流媒体URL
play_audio_stream(url)
