下面是Python程序,可以打印出10行的杨辉三角:
```python
def print_triangle(n):
triangle = []
for i in range(n):
row = [1] * (i + 1)
triangle.append(row)
for j in range(1, i):
triangle[i][j] = triangle[i-1][j-1] + triangle[i-1][j]
for row in triangle:
print(' '.join(map(str, row)).center(n*2))
print_triangle(10)
```
输出结果为:
```

1 1
1 2 1
1 3 3 1
1 4 6 4 1
1 5 10 10 5 1
