What is a Decorator?

A decorator is a wrapper around a function — it adds extra functionality without changing the original function!

☕ Think of it like: Sprinkling chocolate powder on coffee — The coffee is the same, but with extra decoration on top! 🍫

Basic Decorator example

def surendra(func):      # function తీసుకుంటుంది
    def wrapper():
        print("Before function runs")
        func()               # original function execute
        print("After function runs")
    return wrapper           # wrapper return చేస్తుంది


@surendra
def students_info():
    print("Meera sindhu")
    print("Narendra Boyina")

students_info()  # calling function
