python人工智能代码

以下是一个简单的Python人工智能代码，使用了自然语言处理和机器学习技术：

import nltk
from nltk.chat.util import Chat, reflections

pairs = [
    [
        r"my name is (.*)",
        ["Hello %1, how are you today?"]
    ],
    [
        r"hi|hello|hey",
        ["Hello!", "Hi there!"]
    ],
    [
        r"what is your name?",
        ["My name is ChitGPT. How can I assist you?"]
    ],
    [
        r"how are you?",
        ["I'm doing well, thank you! How about you?"]
    ],
    [
        r"what can you do?",
        ["I can help you with information, answer your questions or just chat with you."]
    ],
    [
        r"bye|goodbye",
        ["Goodbye!", "Have a nice day!"]
    ]
]

chatbot = Chat(pairs, reflections)
chatbot.converse()

这个代码使用了nltk模块中的Chat类来创建一个简单的聊天机器人。pairs列表存储了问题和回答的匹配对，reflections字典用于处理反射（例如"my name is Bob"和"your name is Bob"的回答）。最后调用converse()方法开始会话。
