Have you developed your own decorators for functions or methods?

Yes, I have developed custom decorators for functions and methods in Python. Decorators allow you to wrap a function or method with additional functionality without changing their original code. For example, you can create a decorator for logging function calls:

import functools

def log_calls(func):
    @functools.wraps(func)
    def wrapper(*args, **kwargs):
        print(f"Calling function {func.__name__} with arguments {args} and {kwargs}")
        result = func(*args, **kwargs)
        print(f"Function {func.__name__} returned {result}")
        return result
    return wrapper

@log_calls
def add(a, b):
    return a + b

add(2, 3)

Such a decorator is useful for debugging and monitoring the operation of functions.
