Python Tutorial 2026 | Complete Python Course (Beginner to Advanced) | Telusko - Inner Function in Python | 38

In this video, we’ll understand inner functions (functions defined inside another function) — from syntax to real-world examples. What’s Covered 👇 ▶️ Inner Function Basics: Learn how to define one function inside another and why it’s useful. ▶️ Syntax & Scope: Step-by-step explanation of syntax and scope rules (inner functions are accessible only within their outer function). ▶️ Simple Example: A clean, step-by-step demo showing how to define and call an inner function and observe the output. ▶️ How to Expose Inner Functions Globally: Practical ways to use an inner function outside its outer function — 🔹By returning it from the outer function (function factory pattern) 🔹Or by assigning its reference to a global or outer-level variable (carefully). ▶️ Connection with Decorators: Inner functions are the core of Python decorators — we’ll briefly discuss this connection (in-depth explanation coming in future videos). By the end of this video, you’ll have a clear understanding of inner functions, their scope, and real-world use cases — building a strong foundation for decorators.
