33. Global scope, nested functions
The chapter explores global scope and nested functions in Python programming, emphasizing their importance in managing variable visibility and functionality within various scopes. It introduces the concept of enclosing functions and details how nested functions can access variables from their enclosing scope, thereby enhancing modular programming. Additionally, it covers practical applications and implications of these concepts in coding practices.

What we have learnt
- Understanding global and local scope in Python.
- Function nesting allows inner functions to access variables from their enclosing scope.
- Nested functions can help in creating closures, improving data encapsulation.
Key Concepts
- -- Global Scope
- Refers to variables that are defined in the main body of a script and can be accessed anywhere in the code.
- -- Nested Functions
- Functions defined within other functions; they can access variables from their enclosing functions.
- -- Closure
- A feature in programming where an inner function has access to the outer function’s variables even after the outer function has completed execution.
