🤖 Rubi — Rule-Based Python ChatBot

A beginner-friendly rule-based chatbot built with Python to practice functions, dictionaries, loops, conditions, user input, and the datetime module.

---

🌟 Project Overview

Rubi is a simple command-line chatbot that interacts with the user using predefined rules and responses.

The chatbot can:

• 👋 Greet the user based on the current time
• 🧑 Ask for and use the user's name
• 💬 Respond to predefined questions
• 🧠 Match keywords from user input
• 🔄 Continue the conversation using a loop
• 👋 Exit when the user types bye

This project was created as part of my journey to strengthen my Python fundamentals through hands-on projects.

🧠 How Rubi Works

The chatbot follows a simple rule-based flow:

             👤 User
                │
                ▼
        Enter Name / Question
                │
                ▼
       Convert Input to Lowercase
                │
                ▼
       Check Dictionary Keywords
                │
        ┌───────┴────────┐
        │                │
      Match            No Match
        │                │
        ▼                ▼
  Return Response    Default Response
        │                │
        └───────┬────────┘
                ▼
        Continue Conversation
                │
                ▼
           Type "bye"
                │
                ▼
             👋 Exit

🚀 Getting Started

1️⃣ Clone the Repository

git clone https://github.com/Annu1528/Rubi---Rule-Based-Python-ChatBot

2️⃣ Open the Project

cd rule-based-python-chatbot

3️⃣ Run the Chatbot

python rubi_chatbot.py

💻 Example Conversation

Swagat hai! Enter your name: Anushka

Good Afternoon! Anushka

Namaste! Welcome to Rubi, Your Rule Based ChatBot
You can ask me basic questions. Type 'bye' to exit from the bot

Please ask your question: hello

Bot Response: Hi welcome. How can I help you?

Please ask your question: how are you

Bot Response: I am very fine, ThankYou

Please ask your question: motivate me

Bot Response: Keep going. Every bug of your project makes you a better developer.

Please ask your question: bye

Bot Response: Bye! Have a great day!

🧩 Core Code Logic

Rubi stores its responses inside a Python dictionary:

responses = {
    "hello": "Hi welcome. How can I help you?",
    "how are you": "I am very fine, ThankYou",
    "who are you?": "I am a smart AI ChatBot",
    "motivate me": "Keep going. Every bug of your project makes you a better developer",
    "happy": "Great to hear that!"
}

The chatbot then checks whether a keyword exists inside the user's question:

for eachKey in responses:
    if eachKey in UserQuestion:
        return responses[eachKey]

This makes Rubi a rule-based chatbot rather than a machine-learning chatbot.

📚 Python Concepts Practiced

This project helped me practice:

Variables

name = input(...)
presentHour = datetime.datetime.now().hour

Conditions

if 5 <= presentHour < 12:
    ...
elif 12 <= presentHour < 17:
    ...
else:
    ...

Functions

def getResponseOfBot(UserQuestion):
    ...

Dictionaries

responses = {
    "hello": "...",
    "happy": "..."
}

Loops

while True:
    ...

and:

for eachKey in responses:
    ...

String Methods

UserQuestion.lower()

🎯 Learning Goals

The main goal of this project was not to build a complex AI system.

The goal was to understand how basic Python concepts can work together to build a small, functional application.

Through this project, I practiced:

• Writing reusable functions
• Working with dictionaries
• Handling user input
• Using loops
• Applying conditional logic
• Using Python modules
• Debugging syntax and logic errors
• Structuring a small Python project

---

🔮 Future Improvements

Planned improvements for Rubi:

• Add more conversation rules
• Add help command
• Add current date and time responses
• Add calculator functionality
• Improve keyword matching
• Add better error handling
• Store conversation history
• Add a simple GUI
• Eventually experiment with an actual AI/API-based chatbot

---

🐛 Debugging Lessons

During development, I encountered and fixed issues related to:

• Case-sensitive variable names
• Dictionary access syntax
• Loop control using break
• Ordering of conditions
• Handling user input
• Running the correct Python file

These debugging experiences were an important part of building the project.
