logging time

Using decorator, we can implement logging time function.

In [6]:

def logging_time(original_fn):
    def wrapper_fn(*args, **kwargs):
        verbose = False
        if 'verbose' in kwargs:
            verbose = True
            del kwargs['verbose']
        start_time = time.time()
        result = original_fn(*args, **kwargs)
        elapsed_time = (time.time() - start_time) * 1e3
        if verbose:
            print("WorkingTime[{}]: {:.5f} ms".format(original_fn.__name__, elapsed_time))
            return result
        return result, elapsed_time
    return wrapper_fn

    for i in range(num_step):
        time.sleep(0.001)
        printProgressBar(iteration=i + 1, total=num_step, msg='iteration', length=50)
