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 设定目标

#1.设定目标
what_i_want_to_know = [{"role": "user", "content": f"汇总3个function的aiXpert的结果"}]

2 自定义function,3个

#2.自定义function,3个
def search_baidu(keyword):return f"{keyword}是一个技术博主"def search_google(keyword):return f"{keyword}是一个后端工程师"def search_bing(keyword):return f"{keyword}是一个Python爱好者"

3 接口。自定义function—>ChatGPT

采用Tool的标准写法：

tools = [{"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 run_chat(messages):response = openai.chat.completions.create(model   ="gpt-3.5-turbo-1106",messages=messages,tools   =tools,tool_choice="auto", )return response.choices[0].message

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 = run_chat(what_i_want_to_know)
tool_calls = first_response.tool_calls

6 大结局

# 检查是否需要调用函数
if tool_calls:# 解析所有需要调用的函数及参数what_i_want_to_know.append(first_response)  # 注意这里要将openai的回复也拼接到消息列表里# 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)what_i_want_to_know.append({"tool_call_id": tool_call.id,"role": "tool","name": function_name,"content": function_response,}) print(run_chat(what_i_want_to_know))
