如何从 Python 的输出中打印特定的字典键 [不工作]

原文标题 ：How to Print a specific dictionary-key from output in Python [not working]

我编写了这段代码，使用 Deepgram 将音频转换为文本，并在结果中仅打印 Dictionary 中的转录文本。我正在使用这段代码：

 response = await dg_client.transcription.prerecorded(source,  options)
    print(json.dumps(response, indent=4))

    print(response.keys())
    print(response['results']['channels']['alternatives']['transcript'])

但这一个不起作用。我删除了最后两个键（ [‘alternatives’][‘transcript’] ），然后它就可以工作了。这是输出中的字典：

 "results": {
        "channels": [
            {
                "alternatives": [
                    {
                        "transcript": "Yep. I said it before, and I'll say it again. Life moves pretty fast. You don't stop and look around once in a while. You could miss it.",
                        "confidence": 0.9935537
                    }]

请帮忙，提前谢谢！
