上述代码是获取指定位置的温度，得到结果后将温度传给模型，生成最终的结果：
$python weather.py Prompt: What is the weather today in Shanghai? <think> Okay, the user is asking for the weather in Shanghai today. Let me check the tools provided. There's a function called get_current_weather. The parameters required are location and format. The description mentions getting the weather for a location. Even though the parameters' descriptions are a bit unclear, location is a string, so I should provide "Shanghai" as the location. For format, maybe the user wants a simple response, so I'll use "json" as a common format. I'll call the function with these arguments. </think>
Calling function: get_current_weather Arguments: {'format': 'json', 'location': 'Shanghai'} Function output: 33 <think> Okay, the user asked about the weather in Shanghai today. I called the get_current_weather function with the location set to Shanghai and format as JSON. The response came back as "33". Hmm, that's not a typical weather description. Maybe the API returned a temperature in Celsius? 33°C is quite hot. Let me check if there's more data. Wait, the response was just "33", so maybe the API is broken or there was an error. Alternatively, maybe it's a placeholder. I should inform the user that the information is incomplete. I'll mention the temperature if I assume it's Celsius and note that other details aren't available. Let me make sure to ask them to check again later or try another source. </think>
The current weather in Shanghai is not fully available. However, based on the data received, the temperature is approximately **33°C**. For more detailed information (e.g., humidity, wind speed, or conditions), please check again later or use a dedicated weather service. Let me know if you'd like further assistance! ?️
