# Real-Time Quiz Application

A Python-based real-time quiz application designed to mimic the functionality of **Mentimeter**, allowing a host to control the quiz and participants (clients) to join, answer questions, and receive immediate feedback. The application is built using **Flask** and **Socket.IO** for seamless web-based interaction, and it offers a clean, responsive front-end using **HTML**, **CSS**, and **Bootstrap**.

## Features

- **Real-Time Communication**: Uses **Socket.IO** for instant updates between the host and clients.
- **Participant Management**: Tracks connected clients, showing their usernames and responses in real time.
- **Interactive Host Control**: The host can change questions, see live results, and control the flow of the quiz.
- **Simple and Responsive Front-End**: Clean design using Bootstrap for a pleasant user experience across devices.
- **Scalable Design**: Easily expandable to support more questions, features, and visualizations.

Install dependencies with:

```bash
pip install -r requirements.txt
```

## Application Overview
![](assets/2024-10-21-17-18-28.png)
### Host Interface

The host controls the flow of the quiz:
- **View Questions**: See the current question and available options.
- **Next Question**: Advance to the next question.
- **Live Results**: View participant responses and statistics in real time.

### Client Interface

Participants join the quiz and interact with the questions:
- **Join the Quiz**: Enter a temporary username to participate.
- **Receive Questions**: Answer questions as they appear, with four possible options.
- **Live Feedback**: See the result of each question based on group responses.

## Demonstration

For demonstration purposes, this version includes only **two questions**. The questions are stored in `app.py` as follows:

```python
questions = [
    {"question": "What is the capital of France?", "options": ["Paris", "London", "Berlin", "Rome"]},
    {"question": "What is the largest planet?", "options": ["Earth", "Mars", "Jupiter", "Saturn"]}
]
```

### Adding More Questions

To add more questions, simply update the `questions` list in `app.py`. Ensure each question follows the structure:
```python
{"question": "Your question here?", "options": ["Option1", "Option2", "Option3", "Option4"]}
```

## Scaling the Application

This application is built to be easily scalable:
- **Add More Features**: Integrate additional features such as timed questions, answer explanations, or leaderboard tracking.
- **Expand Real-Time Visuals**: Enhance client-side interactivity with more detailed results or progress tracking.
- **Deploy the App**: Use services like **Heroku**, **AWS**, or **Docker** to deploy the application for larger audiences.

## Dependencies

Ensure you have the following dependencies installed, as listed in `requirements.txt`:

```
Flask
Flask-SocketIO
```

### Installing Dependencies

```bash
pip install -r requirements.txt
```

## Troubleshooting

- **No participants showing up**: Ensure all participants join the `/client` interface and submit their usernames correctly.
- **WebSocket issues**: Make sure your firewall or browser settings are not blocking WebSocket connections.
- **Server not starting**: Check that Flask and Flask-SocketIO are installed correctly.
