Have you participated in implementing or using decorators in your past projects?

Yes, I have used decorators in Python to add additional functionality to functions without changing their original code. For example, I used decorators for logging function calls or access rights verification.

Here's a simple decorator example that outputs the execution time of a function:

import time

def timer(func):
    def wrapper(*args, **kwargs):
        start = time.time()
        result = func(*args, **kwargs)
        end = time.time()
        print(f"Execution time of {func.__name__}: {end - start:.4f} seconds")
        return result
    return wrapper

@timer
def some_function():
    time.sleep(1)

some_function()
