、输出以下杨辉三角形（要求输出10行）。（

以下是输出10行杨辉三角形的 Python 代码：

n = 10
# 初始化杨辉三角形第一行
row = [1]
# 遍历杨辉三角形的每一行
for i in range(n):
    # 打印当前行
    print(row)
    # 计算下一行
    next_row = [1]
    for j in range(len(row)-1):
        next_row.append(row[j]+row[j+1])
    next_row.append(1)
    row = next_row

输出结果为：

[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]
