Trivia Quiz Game Project: CLI and GUI Solutions in Python

Trivia Quiz Game:

Develop a trivia quiz game with multiple-choice questions.

From Wikipedia - Trivia is information and data considered of little value. The word is derived from the Latin word triviae, meaning a place where a road splits into two (thus, creating a three-way intersection). It was introduced into English as the adjective trivial in the 15th and 16th centuries.

Modern usage of trivia dates back to the 1960s, when college students introduced question-and-answer contests to their universities. A board game, Trivial Pursuit, was released in 1982 in the same vein as these contests. Since its modern usage, trivia contests have been established at various academic levels as well as in casual venues such as bars and restaurants.

Solution 1: Trivia Quiz Game Using a Command-Line Interface

This solution uses a simple command-line interface (CLI) to prompt the user with multiple-choice questions and collects answers.

Code:

# Solution 1: Trivia Quiz Game Using a Command-Line Interface

def display_question(question_data):
    """Display a question and its options."""
    print(question_data['question'])
    for option in question_data['options']:
        print(option)
    user_answer = input("Select an option (a, b, c, d): ").lower()
    return user_answer

def check_answer(user_answer, correct_answer):
    """Check if the user's answer is correct."""
    if user_answer == correct_answer:
        print("Feedback: Correct!")
        return True
    else:
        print(f"Feedback: Incorrect! The correct answer is {correct_answer}.")
        return False

def main():
    """Main function to run the trivia quiz game."""
    questions = [
        {"question": "What is France's capital?", "options": ["a) Lyon", "b) Marseille", "c) Paris", "d) Nice"], "answer": "c"},
        {"question": "Who painted the Mona Lisa?", "options": ["a) Vincent van Gogh", "b) Leonardo da Vinci", "c) Pablo Picasso", "d) Claude Monet"], "answer": "b"},
        {"question": "What is the tallest mountain in the world?", "options": ["a) K2", "b) Kangchenjunga", "c) Mount Kilimanjaro", "d) Mount Everest"], "answer": "d"},
        {"question": "Who wrote 'Romeo and Juliet'?", "options": ["a) William Shakespeare", "b) Charles Dickens", "c) Jane Austen", "d) Mark Twain"], "answer": "a"},
        {"question": "What is the chemical symbol for water?", "options": ["a) O2", "b) H2O", "c) CO2", "d) NaCl"], "answer": "b"},
    ]
    
    score = 0  # Initialize the score counter
    
    print("Welcome to the Trivia Quiz Game!")
    print("Answer the following questions by selecting the correct option (a, b, c, d):\n")
    
    # Loop through each question in the list
    for question_data in questions:
        user_answer = display_question(question_data)  # Display the question and get user input
        
        # Check if the answer is correct
        if check_answer(user_answer, question_data['answer']):
            score += 1  # Increment score if the answer is correct
    
    # Display the final score
    print(f"\nCongratulations! You have completed the trivia quiz.")
    print(f"Your score is {score} out of {len(questions)}.")

# Run the trivia quiz game
if __name__ == "__main__":
    main()

Solution 2: Trivia Quiz Game with a Graphical User Interface Using PyQt5

This solution uses the PyQt5 library to create a graphical user interface (GUI) for the trivia quiz game.

Code:

# Solution 2: Trivia Quiz Game with a GUI Using PyQt5

from PyQt5.QtWidgets import QApplication, QMainWindow, QVBoxLayout, QWidget, QLabel, QPushButton, QMessageBox, QButtonGroup, QRadioButton
import sys

class TriviaQuizGame(QMainWindow):
    """Class to create a Trivia Quiz Game using PyQt5."""

        # Check if an option is selected
        if not selected_button:
            QMessageBox.warning(self, "No Answer", "Please select an answer before proceeding.")
            return

        # Check if the selected answer is correct
        user_answer = selected_button.text()[0].lower()
        correct_answer = self.questions[self.current_question]['answer']
        
        if user_answer == correct_answer:
            self.score += 1
            QMessageBox.information(self, "Feedback", "Correct!")
        else:
            QMessageBox.information(self, "Feedback", f"Incorrect! The correct answer is {correct_answer.upper()}.")

        # Move to the next question or show the final score
        self.current_question += 1

            self.close()

# Run the PyQt5 trivia quiz game
app = QApplication(sys.argv)
window = TriviaQuizGame()
window.show()
sys.exit(app.exec_())

Output:

Explanation:

• PyQt5 Setup:
• Initializes the PyQt5 main window, sets the title, and sets up the interface layout using widgets.
• Question Handling:
• Displays each question and options as radio buttons, allowing the user to select an answer.
• Next Button Functionality:
• When the user clicks "Next," the application checks if an answer is selected, provides feedback, and moves to the next question.
• Final Score Display:
• At the end of the quiz, a message box displays the final score.

Both solutions create a Trivia Quiz Game with multiple-choice questions, one using a command-line interface (CLI) and the other using a graphical user interface (GUI) with PyQt5. Each solution provides a different user experience while accomplishing the same core functionality of a trivia quiz game.
