Reducing Excessive Function Arguments: A Practical Guide

💡 Learn how to design great software in 7 steps: https://arjan.codes/designguide.

Tired of passing five arguments to every function? In this video, I clean up a realistic Python codebase using the Context Object Pattern. You’ll see how to go from messy, repetitive function signatures to a cleaner and more maintainable design. We’ll introduce context objects, explore how they help reduce parameter bloat, discuss the trade-offs (like increased coupling), and show how to use Protocols to keep things decoupled and testable.
