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.
