Python Python Decorators

The output is not always the same although it should be!

The order in which my logging.debug line and the code block of multiply_by_five is executed keeps switching. I don't understand the steps that occur when I use '@'. Does the decorator run first, then the code block of function the decorator was put. Because in this case the number 215 should never be outputted to the console before the logging.debug line. Either way, can you explain to me what happens once I call multiply_by_five(43). Thanks :)

def logme(func):
    import logging
    logging.basicConfig(level=logging.DEBUG)

    def inner(*args, **kwargs):
        logging.debug('Called {} with args {} and kwargs {}'.format(func.__name__, args, kwargs))
        return func(*args, **kwargs)

    return inner


@logme
def multiply_by_five(num):
    return num * 5


print(multiply_by_five(43))
