一、效果展示

话不多说先上效果

为了更有意境我加了个完美的背景来衬托出月饼的好看

我的月饼画的不圆的原因是我故意的，为什么呢？

因为月有阴晴圆缺啊！哈哈！

上面是直接画的，没有填充，接下来我们画一个有填充的。

也可以添加好看的背景噢。

二、程序代码

代码将在下面解释，可以看着代码对应下面的函数解释。

第一种：

import turtle
import math
turtle.title("照彻乾坤，印透山河")
turtle.bgpic("yueliang/1.png")

p = turtle.Turtle()
p.pensize(4)
p.speed(3)

#做月饼的面
def ellipse(a,b,n=500,c='#CD950C'):
    p.penup()
    p.setpos(a,0)

    color = p.color(c)
    p.pendown()

    for i in range(n):
        radian = 2 * math.pi /n
        theta = (i+1) * radian
        next_point = (a * math.cos(theta)),b * math.sin(theta)
        p.setpos(next_point)

ellipse(300,200,c='#CD950C')

三、素材背景

将图片放在文件夹中

本文将1.png放在yueliang文件夹中

1.png

2.png

3.png

更多的背景可以在网上搜索获得。

四、原理解释

1、概念

turtle（海龟）是Python重要的标准库之一，它能够进行基本的图形绘制，其概念诞生于1969年。turtle是最有价值的程序设计入门实践库,它是程序设计入门层面最常用的基本绘图库。

turtle的绘图原理：

有一只海龟处于画布正中心，由程序控制在画布上游走；

海龟走过的轨迹形成了绘制的图形

海龟由程序控制，可改变其大小，颜色等

使用 import 保留字对 turtle 库的引用以下方式：

import turtle

2、函数

窗体函数

turtle.setup()函数与窗体有关，定义如下：

turtle.setup(width,height,startx,starty)

作用：设置主窗体的大小和位置

参数：

• width:窗口宽度。如果值是整数，表示像素值；如果值是小数，表示窗口宽度与屏幕的比例
• height:窗口高度。如果值是整数，表示像素值；如果值是小数，表示窗口高度与屏幕的比例
• startx：窗口左侧与屏幕右侧的像素距离。如果值是None，窗口位于屏幕水平正中央。

 画笔状态函数

画笔运动函数

颜色代码大全

可以选择自己喜欢的颜色画。
