在Python中，可以使用turtle库来绘制海龟图形。下面是一个示例代码，演示如何绘制一个简单的海龟形状：
python
import turtle
# 创建一个海龟对象
my_turtle = turtle.Turtle()
# 设置画布大小
turtle.setup(800, 600)
# 设置画笔颜色和尺寸
my_turtle.pensize(3)
my_turtle.color("green")
# 绘制头部
my_turtle.circle(50)
# 绘制眼睛
my_turtle.penup()
my_turtle.goto(-20, 100)
my_turtle.pendown()
my_turtle.circle(10)
my_turtle.penup()
my_turtle.goto(20, 100)
my_turtle.pendown()
my_turtle.circle(10)
# 绘制身体
my_turtle.penup()
my_turtle.goto(-50, -50)
my_turtle.pendown()
my_turtle.forward(100)
# 绘制四条腿
my_turtle.penup()
my_turtle.goto(-50, -100)
my_turtle.pendown()
my_turtle.forward(30)
my_turtle.penup()
my_turtle.goto(-20, -100)
my_turtle.pendown()
my_turtle.forward(30)
my_turtle.penup()
my_turtle.goto(20, -100)
my_turtle.pendown()
my_turtle.forward(30)
my_turtle.penup()
my_turtle.goto(50, -100)
my_turtle.pendown()
my_turtle.forward(30)
# 隐藏海龟
my_turtle.hideturtle()
# 关闭窗口
turtle.done()
运行上述代码，将会弹出一个窗口显示绘制的海龟形状。你可以根据需要修改代码来绘制更复杂的海龟图案。
