A simple rule-based chatbot built in Python, created as part of the CodeAlpha Python Programming Internship (Task 4).

This program simulates a basic conversation using keyword matching. The user types a message, and the chatbot replies based on predefined rules — no AI or external libraries required.

• Responds to greetings, "how are you", name questions, and thanks
• Case-insensitive and forgiving input matching (e.g. "Hello!" and "hello" both work)
• Multiple exit keywords: bye, goodbye, exit, quit
• Handles empty input gracefully
• Improved version includes varied, randomized responses for a more natural feel

• Functions
• if-elif-else conditional logic
• while loops
• Input/output handling
• Lists and the in operator
• random.choice() for response variety (improved version)

• Python 3.7 or higher (no external libraries needed)

1. Clone this repository:

   git clone https://github.com/<your-username>/CodeAlpha_BasicChatbot.git
   cd CodeAlpha_BasicChatbot

2. Run the script:

   python chatbot.py

   Or run the improved version:

   python chatbot_improved.py

3. Type a message and press Enter. Try:
   • hello
   • how are you
   • what is your name
   • thanks
   • bye (to end the conversation)

Chatbot: Hello! I'm your CodeAlpha chatbot.
Chatbot: Type 'bye' anytime to end our conversation.

You: hello
Chatbot: Hi! How can I help you today?

You: how are you
Chatbot: I'm fine, thanks! How about you?

You: bye
Chatbot: Goodbye! Have a great day.
