Build a basic chatbot

Creating a basic chatbot involves writing a program that can take user input, process it, and respond appropriately. Below is a simple example of a rule-based chatbot in Python. This chatbot uses predefined responses based on keywords found in the user’s input.

# Basic Chatbot in Python

def chatbot_response(user_input):
    user_input = user_input.lower()

    if "hello" in user_input or "hi" in user_input:
        return "Hello! How can I assist you today?"
    elif "how are you" in user_input:
        return "I'm just a bot, but I'm doing great! How about you?"
    elif "your name" in user_input:
        return "I'm ChatBot, your virtual assistant."
    elif "bye" in user_input or "exit" in user_input:
        return "Goodbye! Have a great day!"
    else:
        return "Sorry, I didn't understand that. Can you please rephrase?"

def main():
    print("Welcome to the Basic Chatbot! Type 'exit' or 'bye' to end the conversation.")
    while True:
        user_input = input("You: ")
        response = chatbot_response(user_input)
        print("Bot:", response)
        if user_input.lower() in ["exit", "bye"]:
            break

if __name__ == "__main__":
    main()

This chatbot responds to greetings, questions about its name, and farewells. It handles unknown inputs with a default message.
