Automate Your E-Learning Quiz Creation: A Python Script for Interactive Choice Images

Introduction: The Challenge of Creating Engaging Quiz Visuals

As an e-learning developer and instructional designer, I constantly face the challenge of creating engaging, interactive content that keeps learners motivated. One particular pain point I encountered was generating hundreds of quiz choice images for a gamified learning platform I was developing.

The scenario was this: I had a bug-themed educational game where learners needed to select answers by clicking on different cartoon bugs. Each question had multiple choice options (A, B, C), and I needed to create unique images combining:

• Placeholder images (cute bug characters)
• Text option images (the actual answer choices)
• Consistent formatting across all questions
• Randomized bug assignments to keep things interesting

Doing this manually would have taken weeks. So, I created a Python script that automated the entire process. Today, I’m sharing both the original simple script and an enhanced version that other e-learning professionals can adapt for their own projects.

The Problem: Manual Image Creation is Time-Consuming

What I Started With:

• 20 questions with 3-4 options each (60+ individual images needed)
• 3 different bug character images (bug 1.png, bug 2.png, bug 3.png)
• Text option images for each choice (Q01-O1@3x.png, Q01-O2@3x.png, etc.)
• A need for consistent positioning and formatting

What I Needed:

• Automated combination of bug images with text options
• Organized output with clear filenames
• Randomized bug assignments for variety
• Scalable solution for future quiz expansions

The Solution: Python Automation with PIL

How It Works:

1. File Organization: Scans the Options directory for question files following the pattern Q##-O#@3x.png
2. Grouping: Groups options by question number (Q01, Q02, etc.)
3. Random Assignment: Randomly assigns bug images to each option
4. Image Composition: Overlays text options onto bug images
5. Output Organization: Saves results in organized folders with clear naming

Key Improvements:

1. Configuration Management: JSON-based configuration for easy customization
2. Error Handling: Robust error handling with meaningful messages
3. Flexible Positioning: Multiple text positioning options
4. Better File Management: Improved organization and validation
5. Statistics Reporting: Detailed generation statistics
6. Type Hints: Professional code documentation

How to Use This Script for Your Projects

Step 1: Prepare Your Assets

File Structure:

YourProject/
├── Options/
│   ├── bug1.png          # Your placeholder images
│   ├── bug2.png
│   ├── bug3.png
│   ├── Q01-O1@3x.png     # Question 1, Option A
│   ├── Q01-O2@3x.png     # Question 1, Option B
│   ├── Q01-O3@3x.png     # Question 1, Option C
│   ├── Q02-O1@3x.png     # Question 2, Option A
│   └── ...
├── script.py             # Your Python script
└── GeneratedChoices/     # Output folder (auto-created)

Step 2: Install Dependencies

pip install Pillow

Step 3: Customize for Your Needs

For Different Themes: Replace the bug images with your theme:

• Characters (robots, animals, people)
• Objects (books, tools, vehicles)
• Abstract shapes (geometric forms, icons)

For Different File Naming: Modify the grouping logic to match your naming convention:

# For files like "Chapter1_OptionA.png"
q_num = f.split('_')[0]

# For files like "lesson-01-choice-a.png"
parts = f.split('-')
q_num = f"{parts[0]}-{parts[1]}"

Step 4: Run the Script

Simple Usage:

# Just run with default settings
python script.py

Advanced Usage:

from enhanced_quiz_generator import QuizImageGenerator

# Create with custom configuration
generator = QuizImageGenerator("my_config.json")
stats = generator.generate_all_images()
print(f"Generated {stats['total_images']} images!")

Real-World Applications Beyond Quizzes

This script isn’t limited to quiz creation. Here are other e-learning applications:

1. Interactive Scenarios

• Character + dialogue combinations
• Branching story visuals
• Role-play scenario images

2. Vocabulary Learning

• Word + visual associations
• Language learning flashcards
• Cultural context imagery

3. Product Training

• Product images + feature callouts
• Process steps + visual guides
• Safety procedures + warning overlays

4. Assessment Varieties

• True/False with visual cues
• Matching exercises
• Sequence ordering activities

Configuration Options Explained

The enhanced script offers extensive customization through JSON configuration:

{
    "options_dir": "./Assets",
    "output_dir": "./FinalImages",
    "placeholder_images": ["character1.png", "character2.png"],
    "text_position": "bottom_center",
    "text_width_ratio": 0.9,
    "text_height_ratio": 0.3,
    "padding": 15
}

Configuration Parameters:

• options_dir: Where your source images are stored
• output_dir: Where generated images will be saved
• placeholder_images: List of your character/background images
• text_position: Where text appears (top_center, bottom_center, center)
• text_width_ratio: Text width as percentage of placeholder width
• text_height_ratio: Text height as percentage of placeholder height
• padding: Space between text and image edges

Performance and Scalability

Performance Metrics from My Project:

• 20 questions × 3 options = 60 images
• Generation time: ~5 seconds
• File size: Consistent 150-300KB per image
• Memory usage: Minimal (processes one image at a time)

Scalability Considerations:

• 100+ questions: No performance issues
• Large image files: Consider resizing source images first
• Multiple themes: Use separate configuration files
• Batch processing: The script handles unlimited questions automatically

Troubleshooting Common Issues

Issue 1: “IndexError: list index out of range”

Cause: Questions with different numbers of options Solution: The enhanced script automatically handles this with idx % len(bug_images)

Issue 2: “FileNotFoundError”

Cause: Missing placeholder or option images Solution: The enhanced script provides detailed warnings about missing files

Issue 3: Poor Image Quality

Cause: Incorrect resize ratios Solution: Adjust text_width_ratio and text_height_ratio in configuration

Issue 4: Text Positioning Problems

Cause: Different placeholder image sizes Solution: Use the text_position and padding settings to fine-tune placement

Advanced Customizations

Adding Background Effects

def add_background_effect(self, text_img: Image.Image) -> Image.Image:
    """Add semi-transparent background for better text readability."""
    background = Image.new('RGBA', text_img.size, (255, 255, 255, 128))
    return Image.alpha_composite(background, text_img)

Custom Text Positioning

def custom_position(self, placeholder_size, text_size, option_index):
    """Position text based on option index."""
    positions = ["top_left", "top_right", "bottom_center"]
    return self.calculate_position(positions[option_index % 3])

Batch Processing Multiple Projects

def process_multiple_projects(project_configs):
    """Process multiple e-learning projects in sequence."""
    for config in project_configs:
        generator = QuizImageGenerator(config)
        generator.generate_all_images()

Cost Savings and Time Benefits

Manual vs. Automated Comparison:

Manual Creation (Photoshop/Canva):

• Time per image: 5-10 minutes
• 60 images = 5-10 hours of work
• Cost: $500-1000 (designer time)
• Consistency: Variable
• Updates: Time-consuming

Automated with Python:

• Setup time: 30 minutes
• Generation time: 5 seconds total
• Cost: Free (after initial script development)
• Consistency: Perfect
• Updates: Instant regeneration

ROI: The script pays for itself after the first project!
