import turtle
<h1>创建屏幕对象</h1><p>screen = turtle.Screen()
screen.bgcolor("black")  # 背景设为黑色，更突出色彩</p><h1>创建海龟对象</h1><p>t = turtle.Turtle()
t.speed(0)  # 最快速度绘制
t.pensize(5)</p>

colors = ["red", "orange", "yellow", "green", "blue", "indigo", "violet"]
<p>for i in range(100):
t.pencolor(colors[i % len(colors)])  # 循环使用颜色
t.forward(i * 2)
t.right(45)</p>

# 抬起画笔，移动到蛇头位置
t.penup()
t.pencolor("white")
t.goto(150, -80)
t.pendown()
<h1>画蛇头（大圆）</h1><p>t.dot(40)</p><h1>画眼睛</h1><p>t.pencolor("black")
t.dot(10)</p>
