Too Many Function Arguments? Use This Pattern
💡 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. 🔥 GitHub Repository: https://git.arjan.codes/2025/context. 🎓 ArjanCodes Courses: https://www.arjancodes.com/courses. 💬 Join my Discord server: https://discord.arjan.codes. ⌨️ Keyboard I’m using: https://amzn.to/49YM97v. 🔖 Chapters: 0:00 Intro 1:07 The Before Version: Too Many Arguments 3:43 Introducing the Context Object Pattern 9:35 But Wait — Aren't We Adding a Bunch of Coupling? 10:56 Making a Distinction Between High-Level vs Low-Level Code 13:33 High-Level Convenience, Low-Level Clarity 15:07 Using Abstraction 17:22 When Should You Use Context Objects? 18:51 Final Thoughts #arjancodes #softwaredesign #python
