我正在生成一个随机数据集。我的数据集是连续的，并且有上限和下限。在某些随机点，我希望我的数据集具有高于和低于限制的异常值。这是我的代码。

generated_data = (12) * np.random.rand(100) + 630
outlier_data = (12) * np.random.rand(20) + (*HERE'S THE PROBLEM)
merged_data = np.concatenate((generated_data, outlier_data))

之后，我想我会重新整理 merged_data。但我不知道如何正确生成异常值。

start = int(time.time())

while True:  

    if int(time.time()) % 2 == 0:
        img = ImageGrab.grab()
        saveas = 'screenshot' + str(int(time.time())) + '.png'
        img.save(saveas)

    elif start + 30 == int(time.time()):
        break

result : https://i.stack.imgur.com/Aqdv6.png

Hi guys. It's a simple code but not working accurately. I wanted to save a screenshot of my screen for every 2 seconds. but in the result, I have some of those odd second files like 'screenshot1552893309.png'. What should I do to fix it?
