5. Decorators

This section provides an in-depth exploration of Python decorators, a powerful feature that allows for the modification and enhancement of function behavior. Participants will learn how to write their own decorators, understand built-in decorators, and apply decorators in practical scenarios.

Local Variable

A local variable is defined inside a function. You cannot access this variable outside the function's definition.

The output is:

The <strong>message</strong> variable is not accessible in the global scope; it exists only inside the function. When the function exits, this variable ceases to exist.
