Add __repr__ methods for better terminal display#127
Merged
Conversation
- Add __repr__ to Demand class showing economic notation (e.g., "Demand: P = 10 - Q") - Add __repr__ to Supply class with proper sign handling (e.g., "Supply: P = 2 + Q") - Add __repr__ and _repr_latex_ to PPF class for both terminal and Jupyter display - Handle special cases: perfectly elastic (P = constant), perfectly inelastic (Q = constant) - Format piecewise functions appropriately These changes ensure economics students see familiar notation in terminals while preserving the beautiful LaTeX display in Jupyter notebooks. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
- Fix bug in Supply repr where negative intercepts weren't handled correctly - Use :g formatting for clean number display (no unnecessary decimals) - Use :+g formatting pattern for automatic sign handling - Add comprehensive test suite for all repr methods - Handle edge cases elegantly (perfectly elastic, piecewise, etc.) The repr methods now show beautiful economic notation: - 'Demand: P = 10-Q' instead of 'Demand: P = 10.0 - 1.0Q' - 'Supply: P = 2+Q' with proper sign handling - 'PPF: y = 20-2x' in standard form 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
