用于以 Z 形式打印矩阵的Python程序

给定一个 n*n 阶的方阵，我们需要以 Z 形式打印矩阵的元素

Examples:
Input : mat[][] =  {1, 2, 3,
                    4, 5, 6,
                    7, 8, 9}
Output : 1 2 3 5 7 8 9

Input : mat[][] = {5, 19, 8, 7,
                   4, 1, 14, 8,
                   2, 20, 1, 9,
                   1, 2, 55, 4}
Output: 5 19 8 7 14 20 1 2 55 4

# Python program to print a 
# square matrix in Z form
  
arr = [[4, 5, 6, 8], 
        [1, 2, 3, 1], 
        [7, 8, 9, 4], 
        [1, 8, 7, 5]]
  
n = len(arr[0])
                   
i=0
for j in range(0, n-1):
    print(arr[i][j], end =" ") 
          
k = 1
for i in range(0, n):
    for j in range(n, 0, -1):
        if(j==n-k):
            print(arr[i][j], end = " ") 
            break; 
    k+=1
  
# Print last row
i=n-1; 
for j in range(0, n):
    print(arr[i][j], end = " ")

输出：

4 5 6 8 3 8 1 8 7 5
