下面是一个5阶的螺旋方阵。编写程序打印此形式的n（n<10）阶的方阵。 （顺时针方向旋进） 1 2 3 4 5 16 17 18 19 6 15 24 25 20 7 14 23 22 21 8 13 12 11 10 9

以下是一个用Python编写的打印螺旋方阵的程序，可以根据输入的阶数来打印对应阶数的螺旋方阵：

def print_spiral_matrix(n):
    matrix = [[0] * n for i in range(n)]
    count = 1
    row_start, row_end, col_start, col_end = 0, n-1, 0, n-1

    while row_start <= row_end and col_start <= col_end:
        for i in range(col_start, col_end+1):
            matrix[row_start][i] = count
            count += 1
        row_start += 1

        for i in range(row_start, row_end+1):
            matrix[i][col_end] = count
            count += 1
        col_end -= 1

        if row_start <= row_end:
            for i in range(col_end, col_start-1, -1):
                matrix[row_end][i] = count
                count += 1
            row_end -= 1

        if col_start <= col_end:
            for i in range(row_end, row_start-1, -1):
                matrix[i][col_start] = count
                count += 1
            col_start += 1

    for i in range(n):
        for j in range(n):
            print(matrix[i][j], end='\t')
        print()

# 测试
print_spiral_matrix(5)

输出结果为：

1	2	3	4	5	
16	17	18	19	6	
15	24	25	20	7	
14	23	22	21	8	
13	12	11	10	9

希望这个程序对你有帮助。
