🤖 Deedee — Rule-Based Chatbot

A simple rule-based chatbot developed as part of the CodeAlpha Python Programming Internship (Task 4: Basic Chatbot).

Deedee responds to everyday conversational inputs — greetings, mood check-ins, jokes, laughter, and more — using keyword-based pattern matching. It also remembers the user's name for the duration of the chat and can save the full conversation transcript to a file.

✨ Features

• 👋 Responds to greetings (hello, good morning, good night, etc.)
• 😊 Understands mood-related messages (happy, sad, tired, bored)
• 😂 Detects laughter (haha, lol, lmao, emojis) and reacts accordingly
• 🙋 Remembers the user's name during the conversation (e.g. "my name is Sara")
• 🕒 Tells the current time and date
• 😄 Tells jokes on request
• 🎨 Answers simple fun questions (favorite color, favorite food, age)
• 🔀 Multiple randomized replies per topic, so conversations feel less repetitive
• 📝 Saves the full chat transcript to a .txt file at the end (optional)
• 🎨 Optional colored terminal interface (works without Colorama as well)

🛠️ Technologies Used

• Python 3
• random module (for varied responses)
• datetime module (for time/date replies)
• Colorama (Optional)

Chat transcripts (e.g. chat_transcript_*.txt) are generated automatically if you choose to save them, and are not part of the repository.

▶️ How to Run

1. Make sure Python 3 is installed.
2. Download or clone this repository.
3. Open the project folder in your terminal.
4. Run the following command:

python chatbot.py

5. Start chatting! Try saying things like:
   • hello
   • my name is Sara
   • how are you
   • joke
   • haha that's funny
   • bye (to end the chat)

Optional: Install Colorama for a colored terminal interface.

pip install colorama

The application also works correctly without Colorama (plain text mode).

🎯 Learning Outcomes

This project demonstrates the use of:

• Conditional Statements (if-elif logic via rule matching)
• Functions and Modular Programming
• Loops (continuous chat loop)
• Lists, Tuples, and Dictionaries
• Basic String Processing and Pattern Matching
• File Handling (saving chat transcripts)
• User Input Validation
