1 引 言
绘制哆啦A梦的过程，其实是对哆啦A梦进行拆解的过程，得先构思出他的头部、眼睛、鼻子、嘴巴、胡须、身体、铃铛、口袋、手以及脚等（如下图所示），才能进行下一步的绘画工作。心中有丘壑，方能水到渠成。
本案例通过python自带的集成开发环境IDLE进行编写并运行，主要应用了python的tkinter模块的canvas组件。
Tkinter 模块（Tk 接口）是 Python 的标准 Tk GUI 工具包的接口；
Canvas（画布） 是一个通用的组件，通常用于显示和编辑图形。你可以用它来绘制线段、圆形、多边形，甚至是绘制其它组件。
下面就来详细说明哆啦A梦的绘画过程吧！！！Let's go......
2 绘制过程
2.1 绘制头部
w.create_oval(100,40,300,240,fill = 'blue')
w.create_oval(115,70,285,240,fill = 'white')
2.2 绘制研究
w.create_oval(165,50,200,90,fill = 'white')
w.create_oval(200,50,235,90,fill = 'white')
w.create_oval(185,62,195,77,fill = 'black')
w.create_oval(205,62,215,77,fill = 'black')
w.create_oval(189,65,192,75,fill = 'white')
w.create_oval(208,65,211,75,fill = 'white')
2.3 绘制鼻子
w.create_oval(193,83,207,97,fill = 'red')
2.4 绘制嘴巴
w.create_line(200,97,200,177)
w.create_arc(130,67,270,177,start=-45,extent = -90,style = ARC)
2.5 绘制胡须
w.create_line(180,127,130,127)
w.create_line(220,127,270,127)w.create_line(180,107,140,97)
w.create_line(220,107,260,97)w.create_line(180,147,140,157)
w.create_line(220,147,260,157)
2.6 绘制身体
w.create_rectangle(120,200,280,350,fill = 'blue')
w.create_oval(130,180,270,320,fill='white')w.create_arc(130,180,270,320,outline = 'white',start=45,extent = 90,style = ARC)
2.7 绘制铃铛
w.create_rectangle(125,195,275,205,fill = 'red')
w.create_arc(118,195,132,205,fill = 'red',start = 90,extent = 180)
w.create_arc(268,195,282,205,fill = 'red',start = 90,extent = -180)
w.create_line(125,195,125,205,fill = 'red')
w.create_line(275,195,275,205,fill = 'red')w.create_oval(188,200,212,224,fill='yellow')
w.create_line(188,212,212,212)
w.create_line(190,209,211,209)
w.create_oval(197,215,203,221,fill = 'red')
w.create_line(200,221,200,224)
2.8 绘制口袋
w.create_arc(155,205,245,295,style = PIESLICE,start = 0,extent = -180)
2.9 绘制手脚
#脚
w.create_arc(180,330,220,370,style = PIESLICE,start = 0,extent = 180,fill = 'white',outline = 'white')
w.create_oval(100,332,190,368,fill = 'white')
w.create_oval(210,332,300,368,fill = 'white')
#手
points1 = [
(120,205),
(120,265),
(90,280),
(80,260)
]w.create_polygon(points1,fill = 'blue',outline = 'black')
w.create_oval(55,260,95,300,fill = 'white')points2 = [
(280,205),
(280,265),
(310,280),
(320,260)
]
w.create_polygon(points2,fill = 'blue',outline = 'black')
w.create_oval(345,260,305,300,fill = 'white')
