利用turtle库绘制五星红旗

可以使用以下代码绘制五星红旗：

import turtle

# 设置画布大小
turtle.setup(800, 600)

# 设置画笔颜色和填充颜色
turtle.color("red", "red")

# 绘制矩形
turtle.begin_fill()
turtle.penup()
turtle.goto(-300, 200)
turtle.pendown()
turtle.forward(600)
turtle.right(90)
turtle.forward(400)
turtle.right(90)
turtle.forward(600)
turtle.right(90)
turtle.forward(400)
turtle.end_fill()

# 绘制大星星
turtle.color("yellow", "yellow")
turtle.begin_fill()
turtle.penup()
turtle.goto(-200, 120)
turtle.pendown()
for i in range(5):
    turtle.forward(80)
    turtle.right(144)
turtle.end_fill()

# 绘制四个小星星
turtle.color("yellow", "yellow")
turtle.begin_fill()
turtle.penup()
turtle.goto(-80, 160)
turtle.pendown()
for i in range(5):
    turtle.forward(30)
    turtle.right(144)
turtle.end_fill()

turtle.color("yellow", "yellow")
turtle.begin_fill()
turtle.penup()
turtle.goto(-60, 80)
turtle.pendown()
for i in range(5):
    turtle.forward(30)
    turtle.right(144)
turtle.end_fill()

turtle.color("yellow", "yellow")
turtle.begin_fill()
turtle.penup()
turtle.goto(-60, 0)
turtle.pendown()
for i in range(5):
    turtle.forward(30)
    turtle.right(144)
turtle.end_fill()

turtle.color("yellow", "yellow")
turtle.begin_fill()
turtle.penup()
turtle.goto(-80, -80)
turtle.pendown()
for i in range(5):
    turtle.forward(30)
    turtle.right(144)
turtle.end_fill()

# 隐藏画笔
turtle.hideturtle()

# 显示绘图窗口
turtle.done()

运行以上代码即可绘制出五星红旗。
