输入n：

n = int(input("请输入n，n要求大于5："))

while n <= 5: n = int(input("输入不符合要求，请重新输入n，n要求大于5："))

初始化杨辉三角

yanghui_tri = [[1], [1, 1]]

生成杨辉三角

for i in range(2, n): row = [1] for j in range(1, i): row.append(yanghui_tri[i - 1][j - 1] + yanghui_tri[i - 1][j]) row.append(1) yanghui_tri.append(row)

输出杨辉三角

for row in yanghui_tri: print(row)
