turtle如何画美国盾牌

以下是使用Python中的turtle库绘制美国盾牌的示例代码：

import turtle

# 设置画布大小
turtle.setup(800, 800)

# 定义绘制五角星的函数
def draw_star(x, y, size):
    turtle.penup()
    turtle.goto(x, y)
    turtle.pendown()
    turtle.begin_fill()
    for i in range(5):
        turtle.forward(size)
        turtle.right(144)
    turtle.end_fill()

# 绘制背景色
turtle.penup()
turtle.goto(-400, 400)
turtle.pendown()
turtle.fillcolor("#FFFFFF")
turtle.begin_fill()
turtle.forward(800)
turtle.right(90)
turtle.forward(400)
turtle.right(90)
turtle.forward(800)
turtle.right(90)
turtle.forward(400)
turtle.end_fill()

# 绘制蓝色区域
turtle.penup()
turtle.goto(-200, 200)
turtle.pendown()
turtle.fillcolor("#003399")
turtle.begin_fill()
turtle.forward(400)
turtle.right(90)
turtle.forward(200)
turtle.right(90)
turtle.forward(400)
turtle.right(90)
turtle.forward(200)
turtle.end_fill()

# 绘制白色区域
turtle.penup()
turtle.goto(-150, 150)
turtle.pendown()
turtle.fillcolor("#FFFFFF")
turtle.begin_fill()
turtle.forward(300)
turtle.right(90)
turtle.forward(150)
turtle.right(90)
turtle.forward(300)
turtle.right(90)
turtle.forward(150)
turtle.end_fill()

# 绘制五颗白色五角星
turtle.penup()
turtle.goto(-120, 60)
turtle.pendown()
turtle.fillcolor("#FFFFFF")
turtle.begin_fill()
draw_star(-120, 60, 40)
turtle.end_fill()

turtle.penup()
turtle.goto(40, 60)
turtle.pendown()
turtle.fillcolor("#FFFFFF")
turtle.begin_fill()
draw_star(40, 60, 40)
turtle.end_fill()

turtle.penup()
turtle.goto(-120, -30)
turtle.pendown()
turtle.fillcolor("#FFFFFF")
turtle.begin_fill()
draw_star(-120, -30, 40)
turtle.end_fill()

turtle.penup()
turtle.goto(40, -30)
turtle.pendown()
turtle.fillcolor("#FFFFFF")
turtle.begin_fill()
draw_star(40, -30, 40)
turtle.end_fill()

turtle.penup()
turtle.goto(-40, -120)
turtle.pendown()
turtle.fillcolor("#FFFFFF")
turtle.begin_fill()
draw_star(-40, -120, 40)
turtle.end_fill()

# 绘制红色和白色条纹
turtle.penup()
turtle.goto(-400, 100)
turtle.pendown()
turtle.fillcolor("#FFFFFF")
turtle.begin_fill()
turtle.forward(800)
turtle.right(90)
turtle.forward(100)
turtle.right(90)
turtle.forward(800)
turtle.right(90)
turtle.forward(100)
turtle.end_fill()

turtle.penup()
turtle.goto(-400, 0)
turtle.pendown()
turtle.fillcolor("#FF0000")
turtle.begin_fill()
turtle.forward(800)
turtle.right(90)
turtle.forward(100)
turtle.right(90)
turtle.forward(800)
turtle.right(90)
turtle.forward(100)
turtle.end_fill()

turtle.penup()
turtle.goto(-400, -100)
turtle.pendown()
turtle.fillcolor("#FFFFFF")
turtle.begin_fill()
turtle.forward(800)
turtle.right(90)
turtle.forward(100)
turtle.right(90)
turtle.forward(800)
turtle.right(90)
turtle.forward(100)
turtle.end_fill()

# 隐藏画笔
turtle.hideturtle()

# 显示绘图窗口
turtle.done()

运行该代码，将会在窗口中绘制出美国盾牌。
