python - 如何在请求响应中获取字符串的内容？

Question

我正在编写一个基于 GPT-2 的 webapp，但它并不好，所以我决定改用官方的 OpenAI GPT-3。所以我提出这个要求：

response = openai.Completion.create(
  engine="davinci",
  prompt="Hello",
  temperature=0.7,
  max_tokens=64,
  top_p=1,
  frequency_penalty=0,
  presence_penalty=0
)

当我打印响应时，我得到了这个：

{
  "choices": [
    {
      "finish_reason": "length",
      "index": 0,
      "logprobs": null,
      "text": ", everyone, and welcome to the first installment of the new opening"
    }
  ],
  "created": 1624033807,
  "id": "cmpl-3CBfb8yZAFEUIVXfZO90m77dgd9V4",
  "model": "davinci:2020-05-03",
  "object": "text_completion"
}

但是我只想打印文本，那么我该怎么做才能打印响应列表中的“文本”值。提前谢谢你，祝你有美好的一天。

Answer 1

使用 dict 键索引和列表索引索引

x = {"choices": [{"finish_reason": "length",
                  "text": ", everyone, and welcome to the first installment of the new opening"}], }

text = x['choices'][0]['text']
print(text)  # , everyone, and welcome to the first installment of the new opening
