我们可以使用random.randint()函数来生成随机整数。 importrandomdefgenerate_random_array(length,min_value,max_value):array=[]for_inrange(length):number=random.randint(min_value,max_value)array.append(number)returnarray# 生成
Working with random numbers is a common task in Python, especially when doing data analysis or building simulations. As someone who has worked extensively with NumPy for over a decade, I’ve found its random number generation capabilities to be highly useful and flexible. In this tutorial, I’...
