首先我们询问 Gemini（最后一句要求它不要生成额外的文本）

1. # ask Gemini
2. model = genai.GenerativeModel('gemini-pro')
3. chat = model.start_chat(history=[])
5. response = chat.send_message('%s -- Please answer as concisely as you can, avoiding any extra conversation or text' % text)
6. gemini_response = response.text

然后我们询问 ChatGPT（最后一句要求它不要生成额外的文本）

1. # ask ChatGPT
2. completion = client.chat.completions.create(
3.   model="gpt-3.5-turbo",
4.   messages=[

14.     a = math.sin(dlat / 2) ** 2 + math.cos(lat1) * math.cos(lat2) * math.sin(dlon / 2) ** 2
