Basic Chatbot

A simple Python rule-based chatbot built for CodeAlpha – Python Programming Internship (Task 4).

Author: Adarsh Singh

Goal

Build a simple rule-based chatbot that responds to basic user messages.

How It Works

• The user types a message in the console.
• The bot checks the message for certain keywords (like "hello", "how are you", "bye", "joke", "weather", "help").
• Based on the keyword matched, it replies with a predefined response.
• If no keyword matches, it gives a fallback response.
• The conversation ends when the user types "bye" or "goodbye".

Key Concepts Used

• if-elif conditionals
• Functions
• Loops
• Input/Output

How to Run

1. Make sure you have Python 3 installed.
2. Download basic_chatbot.py from this repo.
3. Open a terminal in that folder and run:

   python basic_chatbot.py
   

4. Type messages like hello, how are you, tell me a joke, or bye to chat with the bot.

Example Conversation

You: hello
Bot: Hi! How can I help you today?
You: how are you
Bot: I'm fine, thanks! How about you?
You: tell me a joke
Bot: Why do programmers prefer dark mode? Because light attracts bugs!
You: bye
Bot: Goodbye! Have a great day.
