19.8 Development Approach

Step 1: Design Question Structure

Create a clear format:

def create_question(text, options, correct, explanation=""):
    """Create a question dictionary"""
    return {
        "question": text,
        "options": options,  # List of 4 options
        "correct": correct,  # Index of correct option (0-3)
        "explanation": explanation,
        "answered": False,
        "user_answer": None
    }

# Example question
q1 = create_question(
    "What is the capital of France?",
    ["London", "Berlin", "Paris", "Madrid"],
    2,  # Paris is at index 2
    "Paris has been the capital of France for over 1000 years."
)

Step 2: Core Game Functions

Build essential mechanics:

def display_question(question, question_num, total_questions):
    """Display a question nicely formatted"""
    print(f"\nQuestion {question_num} of {total_questions}")
    print("=" * 40)
    print(f"\n{question['question']}\n")
    
    for i, option in enumerate(question['options']):
        letter = chr(65 + i)  # Convert 0,1,2,3 to A,B,C,D
        print(f"{letter}) {option}")

def get_user_answer():
    """Get and validate user's answer"""
    while True:
        answer = input("\nYour answer (A-D): ").upper()
        if answer in ['A', 'B', 'C', 'D']:
            return ord(answer) - 65  # Convert A,B,C,D to 0,1,2,3
        print("Please enter A, B, C, or D.")

def check_answer(question, user_answer):
    """Check if answer is correct and show feedback"""
    question['answered'] = True
    question['user_answer'] = user_answer
    
    if user_answer == question['correct']:
        print("\n✅ CORRECT! Well done!")
        if question['explanation']:
            print(f"\n💡 {question['explanation']}")
        return True
    else:
        correct_letter = chr(65 + question['correct'])
        print(f"\n❌ Sorry, the correct answer was {correct_letter}.")
        if question['explanation']:
            print(f"\n💡 {question['explanation']}")
        return False

Step 3: Question Bank Management

Load questions from files:

def load_questions(filename):
    """Load questions from a text file"""
    questions = []
    
    try:
        with open(filename, 'r') as file:
            lines = file.readlines()
            
        i = 0
        while i < len(lines):
            if lines[i].strip() and not lines[i].startswith('#'):
                # Parse question format
                question_text = lines[i].strip()
                options = []
                
                # Next 4 lines are options
                for j in range(4):
                    if i + j + 1 < len(lines):
                        options.append(lines[i + j + 1].strip())
                
                # Next line is correct answer (A, B, C, or D)
                if i + 5 < len(lines):
                    correct = ord(lines[i + 5].strip()[0]) - 65
                
                # Optional explanation
                explanation = ""
                if i + 6 < len(lines) and lines[i + 6].strip():
                    explanation = lines[i + 6].strip()
                
                question = create_question(
                    question_text, options, correct, explanation
                )
                questions.append(question)
                
                i += 7  # Move to next question
            else:
                i += 1
                
    except FileNotFoundError:
        print(f"Question file {filename} not found!")
        
    return questions

Step 4: High Score System

Track and save achievements:

def load_high_scores(filename="highscores.txt"):
    """Load high scores from file"""
    scores = {}
    
    try:
        with open(filename, 'r') as file:
            for line in file:
                parts = line.strip().split('|')
                if len(parts) == 3:
                    category, name, score = parts
                    if category not in scores:
                        scores[category] = []
                    scores[category].append({
                        'name': name,
                        'score': int(score)
                    })
    except FileNotFoundError:
        pass
        
    return scores

def save_high_score(category, name, score, filename="highscores.txt"):
    """Add a new high score"""
    with open(filename, 'a') as file:
        file.write(f"{category}|{name}|{score}\n")

19.9 Question File Format

Create readable question files:

# Python Programming Questions
# Format: Question, 4 options, correct letter, explanation

What does the len() function do?
Returns the length of an object
Deletes an object
Creates a new list
Joins two strings
A
The len() function returns the number of items in an object like a string or list.

Which symbol is used for comments in Python?
//
#
/* */
--
B
Python uses the # symbol for single-line comments.

19.10 Game Features

Randomization

import random

def get_quiz_questions(all_questions, num_questions=10):
    """Select random questions for quiz"""
    if len(all_questions) <= num_questions:
        return all_questions[:]
    
    return random.sample(all_questions, num_questions)

Score Calculation

def calculate_score(questions, points_per_question=10):
    """Calculate final score"""
    correct = sum(1 for q in questions if q['answered'] and 
                  q['user_answer'] == q['correct'])
    total = len(questions)
    score = correct * points_per_question
    percentage = (correct / total) * 100
    
    return {
        'correct': correct,
        'total': total,
        'score': score,
        'percentage': percentage
    }

19.11 Debugging Strategy

Common issues and solutions:

File Format Errors

# Problem: Questions don't load correctly
# Solution: Add debug prints
print(f"Loading question: {question_text}")
print(f"Options: {options}")
print(f"Correct: {correct}")

Index Errors

# Problem: Letter conversion fails
user_input = 'E'  # Out of range!

# Solution: Validate input range
if answer in ['A', 'B', 'C', 'D']:
    index = ord(answer) - 65

Which symbol is used for comments in Python? // # /* */ -- B Python uses the # symbol for single-line comments. ``` ## Game Features ### Randomization ```python import random def get_quiz_questions(all_questions, num_questions=10): """Select random questions for quiz""" if len(all_questions) <= num_questions: return all_questions[:] return random.sample(all_questions, num_questions) ``` ### Score Calculation ```python def calculate_score(questions, points_per_question=10): """Calculate final score""" correct = sum(1 for q in questions if q['answered'] and q['user_answer'] == q['correct']) total = len(questions) score = correct * points_per_question percentage = (correct / total) * 100 return { 'correct': correct, 'total': total, 'score': score, 'percentage': percentage } ``` ## Debugging Strategy Common issues and solutions: ### File Format Errors ```python # Problem: Questions don't load correctly # Solution: Add debug prints print(f"Loading question: {question_text}") print(f"Options: {options}") print(f"Correct: {correct}") ``` ### Index Errors ```python # Problem: Letter conversion fails user_input = 'E' # Out of range! # Solution: Validate input range if answer in ['A', 'B', 'C', 'D']: index = ord(answer) - 65 ``` ## Reflection Questions After completing the project: 1. **System Design Reflection** - How do all the pieces work together? - Which part was most challenging to integrate? - How does this compare to Part I projects? 2. **Data Structure Reflection** - Why are dictionaries perfect for questions? - How do lists and dictionaries complement each other? - What other data would benefit from this structure? 3. **User Experience Reflection** - What makes the quiz engaging? - How does immediate feedback help learning? - What features would you add next? ## Extension Challenges If you finish early, try these: ### Challenge 1: Timer Feature Add a countdown timer: - 30 seconds per question - Bonus points for quick answers - Skip to next if time runs out ### Challenge 2: Difficulty Levels Implement difficulty: - Easy: Show 2 options instead of 4 - Medium: Normal 4 options - Hard: No multiple choice, type answer ### Challenge 3: Study Mode Create a learning mode: - Review questions without scoring - Show explanations before answering - Track which topics need work ### Challenge 4: Question Editor Build an in-app editor: - Add new questions through the game - Edit existing questions - Validate question format ## Submission Checklist Before considering your project complete: - [ ] **Core Gameplay**: Questions display, answers checked, score tracked - [ ] **Multiple Categories**: At least 2 topic categories - [ ] **File Integration**: Questions load from files - [ ] **High Scores**: Persistent leaderboard - [ ] **User Experience**: Clear interface and feedback - [ ] **Error Handling**: Graceful file and input handling - [ ] **Code Organization**: Well-structured functions ## Common Pitfalls and How to Avoid Them ### Pitfall 1: Hardcoded Questions **Problem**: Questions embedded in code **Solution**: Always load from external files ### Pitfall 2: Poor Randomization **Problem**: Same questions in same order **Solution**: Use random.shuffle() or random.sample() ### Pitfall 3: Confusing Feedback **Problem**: Unclear if answer was right/wrong **Solution**: Clear visual feedback and explanations ### Pitfall 4: Lost Progress **Problem**: Scores not saved properly **Solution**: Save immediately after game ends ## Project Learning Outcomes By completing this project, you've learned: - How to integrate all Part II concepts into one system - How to design complex program architecture - How to create engaging educational software - How to manage multiple interacting components - How to build extensible, maintainable programs ## Part II Complete! 🎉 Congratulations!
