+# 🧠 Quizzler - Python-Based Quiz Application
+
+## 📌 Overview
+
+**Quizzler** is a Python-based GUI quiz application that fetches trivia questions from an online API and challenges the user with a series of True/False questions. Built using **Tkinter**, the app demonstrates effective use of object-oriented programming, API integration, and interactive UI design in Python.
+
+---
+
+## 🎯 Objective
+
+The primary goal of Quizzler is to:
+- Provide a user-friendly quiz experience.
+- Integrate with the Open Trivia DB API for dynamic question fetching.
+- Showcase modular and scalable code architecture using Python.
+

+## 🧩 Project Structure
+
+<pre>
+quizzler/
+│
+├── main.py # Main file to run the application
+├── ui.py # Handles the GUI logic with Tkinter
+├── quiz_brain.py # Core logic for question handling
+├── data.py # Module for API integration
+└── README.md # Documentation
+</pre>
+
+
+- `main.py`: Initializes the quiz and GUI components.
+- `ui.py`: Manages GUI rendering and button interactions.
+- `quiz_brain.py`: Controls quiz logic, answer checking, and scorekeeping.
+- `data.py`: Fetches quiz questions from the Open Trivia DB API.
+
+---
+
+## 🔌 API Integration
+
+Questions are fetched using a GET request from the [Open Trivia Database API](https://opentdb.com/api_config.php). The app dynamically parses the JSON response and formats it for display.
+
+Example API endpoint:
+> https://opentdb.com/api.php?amount=10&type=boolean
+
+ - You can adjust amount if you want more or less questions. And type also.
+
+---
+
+## 💻 How to Run
+
+### ✅ Prerequisites
+
+- Python 3.x installed on your machine
+- `requests` library (install via pip)
+
+### 🧪 Installation Steps
+
+```bash
+git clone https://github.com/prashantgohel321/Quizzler-Python.git
+cd quizzler
+pip install requests
+```
+
+### Execution
+> python main.py
+
+### Features
+ - Clean and responsive UI with score tracking
+ - Instant feedback with visual cues (color-based)
+ - Real-time data fetching using API
+ - Modular code architecture for scalability
+
