Decorators in Python
Decorators are a powerful feature that let you modify or extend the behavior of functions or methods without changing their code.
They are essentially functions that take another function and return a new function – like wrapping a gift with extra features.
Common uses: logging, timing execution, access control, caching, and more.
Functions as First-Class Objects
Python treats functions like any other object – you can pass them around.
