🤖 Anu - Basic Chatbot with UI

CodeAlpha Internship - Task 4: Basic Chatbot

About

This is a simple rule-based chatbot with a graphical user interface (GUI) built using Python and Tkinter. The chatbot, named Anu, can have basic conversations and perform mathematical calculations.

Features

✅ Conversation Features

• Greetings: "hello", "hi", "hey"
• Status inquiries: "how are you"
• Farewells: "bye", "goodbye"
• Help commands: "help", "what can you do"
• General conversation responses

✅ Mathematical Calculations

The chatbot can perform basic arithmetic operations:

Addition

• 5 + 10 → Returns: "The sum of 5 and 10 is 15"
• add 5 and 10 → Returns: "Addition: 5 + 10 = 15"

Subtraction

• 50 - 20 → Returns: "50 minus 20 equals 30"
• subtract 20 from 50 → Returns: "Subtraction: 50 - 20 = 30"

Multiplication

• 6 * 7 → Returns: "6 multiplied by 7 equals 42"
• multiply 6 by 7 → Returns: "Multiplication: 6 × 7 = 42"

Division

• 100 / 5 → Returns: "100 divided by 5 equals 20"
• divide 100 by 5 → Returns: "Division: 100 ÷ 5 = 20"
• Handles division by zero with error message

How to Run

1. Prerequisites: Make sure Python is installed on your system (Python 3.6 or higher)

2. Run the chatbot:

   python chatbot_anu.py

3. Interact with Anu:

   • Type your message in the input field at the bottom
   • Press Enter or click the Send button
   • Chat with Anu and try mathematical calculations!

Key Concepts Used

✅ if-elif statements

Used in get_response() method to handle different user inputs and route to appropriate responses.

Example from code:

if user_input in ['hello', 'hi', 'hey']:
    return "Hi there! How can I help you today?"
elif user_input in ['how are you', 'how are you?']:
    return "I'm doing great, thank you for asking!"

✅ Functions

• get_response(): Processes user input and returns appropriate response
• process_math(): Handles mathematical calculations
• add_message(): Adds messages to the chat display
• send_message(): Handles the send button click event
• chatbot() / main(): Main function to initialize and run the application

✅ Loops

• while loop: Used in the main program structure for continuous conversation (handled by Tkinter's mainloop())
• The chat continues until the user says "bye" or closes the window

✅ Input/Output

• Input: Text input field and Entry widget for user messages
• Output: ScrolledText widget for displaying the conversation

UI Components

• Header: Blue header bar with bot name
• Chat Display: Scrollable text area showing conversation history
• Input Field: Text input for user messages
• Send Button: Button to send messages

Example Conversation

🤖 Anu: Hi! I'm Anu, your assistant chatbot. 👋

You: hello
🤖 Anu: Hi there! How can I help you today? 🙂

You: 10 + 15
🤖 Anu: The sum of 10 and 15 is 25. ✨

You: multiply 7 by 8
🤖 Anu: Multiplication: 7 × 8 = 56. ✨

You: how are you
🤖 Anu: I'm doing great, thank you for asking! How about you? 😊

You: bye
🤖 Anu: Goodbye! It was nice chatting with you! Have a wonderful day! 👋

└── README.md         # This file

Notes

• The chatbot uses simple pattern matching for understanding user input
• Mathematical operations support both direct expressions (e.g., 5 + 10) and text-based commands (e.g., add 5 and 10)
• The GUI provides a user-friendly interface for interacting with the chatbot
• All error handling is implemented for edge cases (like division by zero)
