Why decorators matter

Why decorators matter#

Objectives#

This section introduces the decorator pattern in context by motivating it from first principles. You will build foundational understanding of functional patterns, higher-order functions, and closures, setting the stage for decorators later.

Pre-requisites#

For this section, it’s assumed you’re already comfortable with some “basic” Python concepts, namely:

  • functions (definition and usage)

  • control flow (conditional statements and loops)

  • variables

No knowledge of decorators is required or assumed.
