Define intents with possible keywords and responses

responses = { "greeting": { "keywords": ["hello", "hi", "hey", "good morning", "good evening"], "responses": ["Hi there!", "Hello!", "Hey!", "Greetings!"] }, "farewell": { "keywords": ["bye", "goodbye", "see you", "exit"], "responses": ["Goodbye!", "See you soon!", "Take care!", "Chat later!"] }, "how_are_you": { "keywords": ["how are you", "how's it going", "how do you do"], "responses": ["I'm just a bot, but I'm doing great!", "All systems go!", "Running smoothly!"] }, "time": { "keywords": ["what time", "current time", "tell me the time"], "responses": [] # Will generate dynamically }, "date": { "keywords": ["what date", "today's date", "current date"], "responses": [] # Will generate dynamically }, "name": { "keywords": ["your name", "who are you"], "responses": ["I'm ChatBot 2.0!", "You can call me AssistantBot.", "I'm your virtual assistant."] }, "joke": { "keywords": ["joke", "make me laugh", "funny"], "responses": [ "Why don’t hospitals allow WiFi?Because they don’t want people pulling the plug just to get a stronger connection", "I told my computer I needed a break, and it said 'No problem – I’ll go to sleep.'", "What do you call 8 hobbits? A hob-byte!" ] }, "default": { "responses": [ "I'm not sure I understand.", "Can you rephrase that?", "I'm still learning, try asking something else." ] } }

Function to detect intent based on keywords

def get_intent(user_input): user_input = user_input.lower() for intent, data in responses.items(): for keyword in data.get("keywords", []): if keyword in user_input: return intent return "default"

Function to generate a response

def generate_response(intent): if intent == "time": return f"The current time is {datetime.datetime.now().strftime('%H:%M:%S')}." elif intent == "date": return f"Today's date is {datetime.datetime.now().strftime('%Y-%m-%d')}." else: return random.choice(responses[intent]["responses"])

Chatbot main function

def chatbot(): print("ChatBot 2.0: Hello! Ask me anything. Type 'bye' to exit.\n")

while True:
    user_input = input("You: ").strip()

    if user_input.lower() in ["bye", "exit"]:
        print("ChatBot 2.0: Goodbye! Have a great day!")
        break

    intent = get_intent(user_input)
    response = generate_response(intent)
    print(f"ChatBot 2.0: {response}")
