以下是绘制圣诞树的Python代码示例： ```python import turtle import random # 设置画笔 tree = turtle.Turtle() tree.speed(0) turtle.bgcolor("white") tree.color("green") # 绘制树干 def draw_trunk(): tree.color("brown") tree.pensize(20) tree.penup() tree.goto(0, -200) tree.pendown() tree.goto(0, -100) # 绘制树叶 def draw_triangle(length): tree.color("green") tree.begin_fill() tree.forward(length) tree.left(120) tree.forward(length) tree.left(120) tree.forward(length) tree.end_fill() # 绘制树 def draw_tree(height): tree.penup() tree.goto(0, -100) tree.pendown() tree.left(90) for i in range(height): draw_triangle(20 * (i + 1)) tree.penup() tree.right(120) tree.forward(20) tree.left(120) tree.pendown() # 绘制装饰物 def draw_decorations(height): colors = ["red", "blue", "yellow", "purple", "orange"] for i in range(height): for j in range(i + 1): tree.penup() tree.goto(-20 * i + 40 * j, -100 + 20 * i) tree.pendown() tree.color(random.choice(colors)) tree.begin_fill() tree.circle(10) tree.end_fill() # 绘制完整的圣诞树 def draw_christmas_tree(height, decorations): draw_tree(height) # Position the turtle for drawing decorations tree.left(90) tree.goto(0, height * 20) tree.right(90) draw_decorations(decorations) # 调用函数绘制圣诞树 draw_trunk() draw_christmas_tree(10, 50) # 隐藏画笔 tree.hideturtle() # 显示绘制结果 turtle.done() ```
