python 画圣诞树

以下是一个使用Python画圣诞树的例子：

def draw_christmas_tree(height):
    for i in range(height):
        print(' ' * (height - i - 1) + '*' * (2 * i + 1))
    print(' ' * (height - 1) + '|')

height = 5
draw_christmas_tree(height)

这段代码会输出一个高度为5的圣诞树，效果如下：

    *
   ***
  *****
 *******
*********
    |
