turtle库绘制五星红旗代码

turtle库是Python中一个常用的绘图库，可以用来进行简单的图形绘制。下面是使用turtle库绘制五星红旗的代码：

import turtle

# 设置画布大小和背景颜色
turtle.setup(800, 600)
turtle.bgcolor("red")

# 绘制大五角星
turtle.penup()
turtle.goto(-180, 60)
turtle.pendown()
turtle.begin_fill()
turtle.color("yellow")
for _ in range(5):
    turtle.forward(60)
    turtle.right(144)
turtle.end_fill()

# 绘制四个小五角星
turtle.penup()
turtle.goto(-120, 90)
turtle.pendown()
turtle.color("yellow")
for _ in range(4):
    turtle.begin_fill()
    for _ in range(5):
        turtle.forward(20)
        turtle.right(144)
    turtle.end_fill()
    turtle.penup()
    turtle.forward(40)
    turtle.pendown()

# 隐藏画笔
turtle.hideturtle()

# 点击关闭窗口退出程序
turtle.exitonclick()

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。

用python 的turtle库绘制五星红旗

好的，下面是用 Python 的 turtle 库绘制五星红旗的代码：

import turtle

# 设置画布大小
screen = turtle.Screen()
screen.setup(800, 500)

# 画红色背景
turtle.penup()
turtle.goto(-400, 250)
turtle.pendown()
turtle.begin_fill()
turtle.color("red")
for i in range(2):
    turtle.forward(800)
    turtle.right(90)
    turtle.forward(500)
    turtle.right(90)
turtle.end_fill()

# 画大星星
turtle.penup()
turtle.goto(-280, 120)
turtle.pendown()
turtle.begin_fill()
turtle.color("yellow")
for i in range(5):
    turtle.forward(100)
    turtle.right(144)
turtle.end_fill()

# 画四个小星星
positions = [(0, 135), (-40, 85), (40, 85), (-40, 35)]
turtle.penup()
turtle.color("yellow")
for position in positions:
    turtle.goto(position)
    turtle.pendown()
    turtle.begin_fill()
    for i in range(5):
        turtle.forward(20)
        turtle.right(144)
    turtle.end_fill()

# 隐藏画笔
turtle.hideturtle()

# 程序结束，持续显示
turtle.done()

运行代码后，就能看到绘制的五星红旗了。如果需要保存图片，可以使用 turtle 库提供的 `getcanvas()` 方法，将画布转换成 tkinter 的 Canvas 对象，再使用 Canvas 对象的 `postscript()` 方法保存成 PS 或 EPS 格式的图片。示例代码如下：

# 保存为 EPS 格式图片
canvas = turtle.getcanvas()
canvas.postscript(file="五星红旗.eps")
