Level: Real World

Your task for today is to build an interactive quiz game using Python classes and a Gradio web interface. This project teaches how to design a system with multiple interconnected classes and wrap it into a user-friendly web app.

📝 Project Task

Core Classes

• Question(text: str, options: list[str], answer: int)
  Represents one question. Stores the text, a list of options, and the index of the correct answer.

• Quiz(questions: list[Question])
  Manages the flow of the game.

  Methods:

  • next_question() → returns the current Question object

  • submit(choice: int) → checks answer, updates score, advances to next

  • reset() → resets all progress and score

  • summary() → returns final score, accuracy, and time taken

Expected Output

This is a web app that uses the Gradio web framework. Here is how the app will look like:

The user can answer questions in the app, submit their answers, and the score in the “Status” tab is updated in real time.

Data

In the example provided in the Jupyter Notebook linked at the bottom of this page we are using these sample data:

# Sample questions
questions = [
    Question("What is the capital of France?", ["Paris", "London", "Berlin"], 0),
    Question("Which language is this quiz written in?", ["Java", "Python", "C++"], 1),
    Question("2 + 2 = ?", ["3", "4", "5"], 1),
    Question("What is the largest planet in our solar system?", ["Earth", "Jupiter", "Saturn"], 1),
    Question("Which year did World War II end?", ["1944", "1945", "1946"], 1)
]
