写一个圣诞树的Python代码

好的，请稍等片刻，我为您生成一个 Python 代码实现圣诞树。

# 导入模块
import random
 
# 定义一个函数，用于绘制一行树叶
def draw_leaves(num):
    for i in range(num):
        print("*", end="")
    print()
 
# 定义函数，用于绘制圣诞树
def draw_tree(num):
    for i in range(num):
        num_of_leaves = i * 2 + 1
        num_of_spaces = num - i
        for j in range(num_of_spaces):
            print(" ", end="")
        draw_leaves(num_of_leaves)
 
# 主程序
if __name__ == '__main__':
    height = random.randint(7,10) # 树的高度随机生成
    draw_tree(height)

运行结果：
