Your score will be updated based on your answers, and feedback will be provided immediately after each question. The game continues until there are no more questions left.

Application Overview

User Interface

The application's UI is built using PyQt5, providing a responsive and visually appealing design. Key components include:

• Question Label: Displays the current question.
• Option Buttons: For multiple-choice questions, four buttons are displayed for each possible answer.
• True/False Buttons: For true/false questions.
• Score Label: Displays the user's current score.

Game Flow

1. Fetch Questions: Questions are fetched from the OpenTDB API when the game starts.
2. Display Question: The current question is displayed along with the corresponding answer options.
3. User Input: The user selects an answer.
4. Provide Feedback: Immediate feedback is given, indicating if the answer was correct or wrong.
5. Update Score: The user's score is updated based on their answer.
6. Next Question: The next question is loaded, and the process repeats until all questions are answered.

Code Structure

Main Window (Main Class)

This class initializes the main window and manages the overall game logic. Key methods include:

• __init__: Sets up the UI and initializes the question bank and quiz logic.
• load_question: Loads and displays the next question, adjusting the UI based on the question type.
• give_feedback: Provides feedback based on the user's answer and updates the score.
• adjust_label_font_size: Dynamically adjusts the font size of the question label to ensure it fits the available space.

Question Handling

Questions are fetched from the OpenTDB API and formatted appropriately for display. The format_question_text method handles the unescaping of HTML entities and formats the options for multiple-choice questions.

Quiz Logic (QuizBrain Class)

Manages the state of the quiz, including the current question and the user's score. Key methods include:

• next_question: Retrieves the next question in the sequence.
• check_answer: Validates the user's answer against the correct answer for the current question.

API Integration

The application fetches questions from the Open Trivia Database (OpenTDB), an open-source API that provides trivia questions across various categories. The API request is made in the following way:

url_base = "https://opentdb.com/api.php?"
amount = "10"
response = requests.get(f"{url_base}amount={amount}")
data = response.json()
question_data = data["results"]

The questions are then processed and used throughout the game.
