Create a simple chatbot with Python

Creating a simple chatbot in Python can be done using basic libraries without any complex setup. Below is a straightforward example of a rule-based chatbot that responds to user input with predefined answers.

# Simple rule-based 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 help you today?"
    elif "how are you" in user_input:
        return "I'm a chatbot, so I'm always good! How about you?"
    elif "bye" in user_input or "exit" in user_input:
        return "Goodbye! Have a great day!"
    elif "your name" in user_input:
        return "I'm a simple chatbot created in Python."
    else:
        return "Sorry, I didn't understand that. Can you please rephrase?"

def main():
    print("Welcome to the simple Python chatbot! Type 'exit' or 'bye' to end.")
    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 checks for keywords in the user’s input and responds accordingly. It runs in a loop until the user types “exit” or “bye”.

If you want, I can also help you build a more advanced chatbot using libraries like nltk or transformers.
