n = int(input("请输入一个大于1的整数n: ")) matrix = [[0] * n for _ in range(n)] num = 1 left, right, top, bottom = 0, n-1, 0, n-1 while num <= n*n: for i in range(left, right+1): matrix[top][i] = num num += 1 for i in range(top+1, bottom+1): matrix[i][right] = num num += 1 for i in range(right-1, left-1, -1): matrix[bottom][i] = num num += 1 for i in range(bottom-1, top, -1): matrix[i][left] = num num += 1 left, right, top, bottom = left+1, right-1, top+1, bottom-1给我加个输出函数

好的，这里是加上输出函数的完整代码：

def print_matrix(matrix):
    for row in matrix:
        print(row)

n = int(input("请输入一个大于1的整数n: "))
matrix = [[0] * n for _ in range(n)]
num = 1
left, right, top, bottom = 0, n-1, 0, n-1
while num <= n*n:
    for i in range(left, right+1):
        matrix[top][i] = num
        num += 1
    for i in range(top+1, bottom+1):
        matrix[i][right] = num
        num += 1
    for i in range(right-1, left-1, -1):
        matrix[bottom][i] = num
        num += 1
    for i in range(bottom-1, top, -1):
        matrix[i][left] = num
        num += 1
    left, right, top, bottom = left+1, right-1, top+1, bottom-1

print_matrix(matrix)

在主程序中增加了一个名为 `print_matrix` 的函数，用于输出二维列表。在主程序中调用该函数即可输出二维列表。

例如，当输入 n=3 时，输出的二维列表为：

1 2 3 
8 9 4 
7 6 5
