输出杨辉三角

下面是输出10行杨辉三角的Python代码：

n = 10
triangle = [[1]]
for i in range(1, n):
    row = [1]
    for j in range(1, i):
        row.append(triangle[i-1][j-1] + triangle[i-1][j])
    row.append(1)
    triangle.append(row)

for row in triangle:
    print(row)

输出结果如下：

[1]
[1, 1]
[1, 2, 1]
[1, 3, 3, 1]
[1, 4, 6, 4, 1]
[1, 5, 10, 10, 5, 1]
[1, 6, 15, 20, 15, 6, 1]
[1, 7, 21, 35, 35, 21, 7, 1]
[1, 8, 28, 56, 70, 56, 28, 8, 1]
[1, 9, 36, 84, 126, 126, 84, 36, 9, 1]
