注：程序运行时，按下鼠标左键就可以在画布上作图，上图 python 字样就是本人所画 ^_^

其它作图函数：

# 多边形、三角形tCanvas.create_polygon((10,100,10,180,100,180),fill='blue')# 文字tCanvas.create_text((150,50),text=u'输出文字',anchor=E) # 位图bmap={1:'error',2:'info',3:'question',4:'hourglass'}for i in bmap:tCanvas.create_bitmap((20*i,20),bitmap=bmap[i]) # 调入图片img=PhotoImage(file='D:/pictures/exam.gif')tCanvas.create_image((200,200),image=img)tCanvas.pack()

这些颜色已经足够多了，但据说装了seaborn扩展的话xkcd_rgb包含的颜色数(有英文名称的)会有更多......
