matrix = [[random.randint(1, 10) for _ in range(3)] for _ in range(3)] print(matrix) 在这个例子中,我们使用列表推导式生成了一个3x3的随机矩阵,矩阵中的每个元素都是1到10之间的随机整数。通过random.randint(1, 10)生成随机整数,并使用列表推导式构建矩阵的行和列。 总结 random模块是Python中一...

Next, we generated a 3×3 2D matrix and filled it with random integers between 1 and 10. Then, we printed both the matrix on the screen. Method 3 of Python Random Number: Using Secrets Module Python 3.6+ provides a module named “secret”. It provides functions for generating ...
