分享下我的思路，基本就是两个for横向和竖向便利
然后就是找规律了

while True:
    try:
        a = int(input())
        num = 0
        # 竖向遍历
        for j in range(a):
            num = num + j
            row = num
            for i in range(j,a):
                row = row+1+i
                # 横向每行输出
                print(row - j,end=" ")
            print("")
    except:
        break
