• color: ANSI-colored terminal output
• markdown: Using Markdown headers
• educational: Emoji-based indicators for better learning experience

2. Bug Fixes

• Fixed condition evaluation in elif statements
• Corrected iteration handling in for loops
• Fixed indentation issues in nested structures

3. Educational Enhancements

• Added emoji indicators for different operations
• Improved explanation messages
• Added iteration limits for better readability
• Better visualization of program flow

4. Code Structure Improvements

• Better organization of formatting logic
• Improved error handling
• Added proper indentation tracking
• Better handling of large iterations

Breaking Changes

This PR includes breaking changes to the interpreter's initialization:

# Old
interpreter = ThinkPyInterpreter(explain_mode=False)

# New
interpreter = ThinkPyInterpreter(
    explain_mode=False,
    format_style="default",
    max_iterations_shown=5
)

Testing Done

• Tested all output styles with various programs
• Verified elif condition evaluation fix
• Tested with large iterations
• Verified educational mode output
• Tested in both terminal and Jupyter environments

Usage Examples

# Educational mode
%%thinkpy --explain --style educational
objective "Test program"
task "Example" { ... }

# Markdown style
%%thinkpy --explain --style markdown
objective "Test program"
task "Example" { ... }

# Limit iterations
%%thinkpy --explain --max-iterations 3
objective "Test program"
task "Example" { ... }

Documentation Updates
