print_Matrix（Python实现）

 num = int(input("Please input a number:"))     #矩阵最外层的值
 n = num*2
 Matrix = [([0] * n)for i in range(n)]
 for i in range(0, num):                           #矩阵深度
     x = num-i
     for j in range(i, n-i):                       #矩阵宽度
         #Matrix[i].insert(j,num-i)
         #Matrix[j].insert(i,num-i)
         #Matrix[n-i-1].insert(j,num-i)
         #Matrix[j].insert(n-i-1,num-i)
         Matrix[i][j] = x
         Matrix[j][i] = x
         Matrix[n-i-1][j] = x
         Matrix[j][n-i-1] = x
 for i in range(0, n):                            #打印矩阵
     for j in range(0, n):
         print(str(Matrix[i][j])+"  ", end='')
     print('\n')

输出结果如下：
