Lesson Briefing

Pyfessor

"This is the Block 1 milestone. Everything you've learned about first-class functions, closures, the decorator pattern, functools.wraps, parameterisation, stacking, class-based decorators, and real-world patterns comes together in one polished module. You're building the decorator engine that every subsequent lesson will depend on — the foundation of the entire budget dashboard. Make it solid, make it documented, make it testable."
