Python decorator making it simple to create decorators with arguments

.py

def arg_decorator(func):
    def wrapper(*args, **kwargs):
        return lambda f: func(f, *args, **kwargs)

    return wrapper

example.py

@arg_decorator
def decorator(func, a, b=None): # function to decorate has to be first argument
    def wrapper(*args, **kwargs):
        if b is not None:
            print(b)
        return func(*args, **kwargs) + a
    return wrapper
