vertical-ordering

Organize Python functions by placing high-level callers first and helper implementations below them. This caller-first ordering makes modules easier to scan and reason about during development and code review.

Vertical ordering in code refactoring is the practice of structuring function definitions so public callers appear above their helpers. It preserves call chains and reduces reader context switches for improved readability.

Reorder functions during a module refactor when extracting helpers, writing new functions, or reorganizing code. Apply caller-first placement to maintain a readable flow and guide shared helper positioning.

The best way to order shared helpers with multiple callers is to place the high-level caller functions above the shared helper implementations. This guides placement and reduces the context switches needed to understand the code.

Yes, you can use vertical ordering for typical Python projects. It applies during writing new functions, extracting helpers, refactoring modules, and reorganizing code to enforce caller-first ordering and preserve call chains.
