如何打印小于特定值的三维数组的值？

def print_array(array, threshold):
    for i in range(len(array)):
        for j in range(len(array[i])):
            for k in range(len(array[i][j])):
                if array[i][j][k] < threshold:
                    print(array[i][j][k])

# 示例三维数组
array = [
    [[1, 2, 3], [4, 5, 6]],
    [[7, 8, 9], [10, 11, 12]],
    [[13, 14, 15], [16, 17, 18]]
]

# 打印小于特定值的元素（例如，打印小于10的元素）
print_array(array, 10)
