倒s型填数，求做法!（）

就是给出n值，要求输出nxn的方阵，s型排列，从左上开始

import numpy as np

n = int(input(""))
Array = np.array(range(1, n * n + 1)).reshape(n, n)
row = 0
line = 0
count1 = 1  # 计数器1用于计算蛇形矩阵填充的数
Max = 2 * n - 2
for total in range(n):
    if total % 2 == 0:
        for row in range(total + 1):
            line = total - row
            Array[row, line] = count1
            count1 = count1 + 1
    else:
        for line in range(total + 1):
            row = total - line
            Array[row, line] = count1
            count1 = count1 + 1

count2 = 1  # 用于画下三角矩阵
for total in range(n, Max + 1):
    if total % 2 == 0:
        for row in range(count2, n):
            line = total - row
            Array[row, line] = count1
            count1 = count1 + 1
        count2 = count2 + 1
    else:
        for line in range(count2, n):
            row = total - line
            Array[row, line] = count1
            count1 = count1 + 1
        count2 = count2 + 1
for line in range(n):
    for row in range(n):
        if row + 1 != n:
            if Array[line, row] < 10:
                print(' ', end='')
            print(Array[line, row], end='  ')
        else:
            if Array[line, row] < 10:
                print(' ', end='')
            print(Array[line, row])
