上一篇解决了调用一个函数的问题。这一篇扩展为调用3个。n个自行脑补。

1 定义参数和函数

#1.设定目标
import json
import openai#1.定义parameters for text completion
ai_prompt = [{"role": "user", "content": f"汇总3个function的aiXpert的结果"}
]#2.定义self-function,3个
def search_baidu(keyword):return f"{keyword}是一个技术博主"def search_google(keyword):return f"{keyword}很牛"def search_bing(keyword):return f"{keyword}喜欢水鱼"#3.设置参数
ai_function = [{"type": "function","function": {"name": "search_baidu","parameters": {"type": "object","properties": {"keyword": {"type": "string",}},"required": ["keyword"],},}},    {"type": "function","function": {"name": "search_google","parameters": {"type": "object","properties": {"keyword": {"type": "string",}},"required": ["keyword"],},}},        {"type": "function","function": {"name": "search_bing","parameters": {"type": "object","properties": {"keyword": {"type": "string",}},"required": ["keyword"],},}}
]available_functions = { "search_baidu": search_baidu, "search_google": search_google, "search_bing": search_bing } #4.define function to call ChatGPT 
def chat_completions(parameter_message):response = openai.chat.completions.create(model   ="gpt-3.5-turbo-1106",messages=parameter_message,tools   =ai_function,tool_choice="auto", )return response.choices[0].message

2 第一轮chatgpt

#5.发起首次请求，告诉gpt要做什么，已经有哪些函数可以调动
first_response = chat_completions(ai_prompt)
tool_calls = first_response.tool_calls

3 第一轮结果和function定义全部加入prompt再喂给chatgpt

# 第一轮chat completions的结果加入prompt，再把function参数加入prompt，然后一起喂给chatgptif tool_calls:ai_prompt.append(first_response)  # 第一轮chat completions的结果加入prompt，# 将所有函数调用的结果拼接到消息列表里for tool_call in tool_calls:function_name = tool_call.function.namefunction_to_call = available_functions[function_name]function_args = json.loads(tool_call.function.arguments)function_response = function_to_call(**function_args)ai_prompt.append({"tool_call_id": tool_call.id,"role": "tool","name": function_name,"content": function_response,}) print(chat_completions(ai_prompt))

4 大结局

ChatCompletionMessage(content='根据三个搜索引擎的结果，"AIxPert" 是一个技术博主，非常牛，也喜欢水鱼。', role='assistant', function_call=None, tool_calls=None)
