输出杨辉三角的前10行
以下是编程输出杨辉三角形的前10行的Python代码:
```python
n = 10 # 前10行
triangle = [[1] * (i + 1) for i in range(n)] # 初始化三角形,每行元素个数为行数加1
for i in range(2, n): # 从第3行开始计算
for j in range(1, i): # 每行第2个元素到倒数第2个元素
triangle[i][j] = triangle[i-1][j-1] + triangle[i-1][j] # 根据上一行计算当前行
# 输出三角形
for row in triangle:
print(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]
```
