如何从数组中的一个点向外循环？

# 假设数组为一维数组
array = [1, 2, 3, 4, 5]
start_index = 0

# 从起始点向外循环
while start_index < len(array):
    current_element = array[start_index]
    print(current_element)
    start_index += 1

# 假设数组为二维数组
array_2d = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]
start_index = 0

# 从起始点向外循环
while start_index < len(array_2d):
    current_row = array_2d[start_index]
    for element in current_row:
        print(element)
    start_index += 1
