1、运用turtle库函数实现绘制不同几何图形，并做填充处理：

# TurtleTest.py
import turtle

def main():
    turtle.speed(2)
    
    turtle.pensize(3)
    turtle.penup()
    turtle.goto(-200,-50)
    turtle.pendown()
    #表示开始做图形填充
    turtle.begin_fill()
    turtle.color('red')
    turtle.circle(40,steps= 3)
    #填充结束
    turtle.end_fill()

    turtle.penup()
    turtle.goto(-100,-50)
    turtle.pendown()
    turtle.begin_fill()
    turtle.color("blue")
    turtle.circle(40, steps=4)
    turtle.end_fill()
 
    turtle.penup()
    turtle.goto(0,-50)
    turtle.pendown()
    turtle.begin_fill()
    turtle.color("green")
    turtle.circle(40, steps=5)
    turtle.end_fill()
 
    turtle.penup()
    turtle.goto(100,-50)
    turtle.pendown()
    turtle.begin_fill()
    turtle.color("yellow")
    turtle.circle(40, steps=6)
    turtle.end_fill()
 
    turtle.penup()
    turtle.goto(200,-50)
    turtle.pendown()
    turtle.begin_fill()
    turtle.color("purple")
    turtle.circle(40)#未设置步数则认为是绘制圆形
    turtle.end_fill()
 
    turtle.color("green")
    turtle.penup()
    turtle.goto(-100,50)
    turtle.pendown()
    turtle.write(("Cool Colorful shapes"),#添加文字
        font = ("Times", 18, "bold"))#设置文字格式
    turtle.hideturtle()#隐藏画笔形状
    
    turtle.done()
    
if __name__ == '__main__':
    main()

 

运行结果：

2、利用turtle绘制图形交互界面，以聊天软件为例;

# UITurtle.py

from tkinter import *
import time

def main():
    def sendMsg():#发送消息
        strMsg = '我：'+time.strftime('%Y-%m-%d %H:%M:%S',time.localtime())+'\n'
        txtMsgList.insert(END,strMsg,'greencolor')
        txtMsgList.insert(END,txtMsg.get('0.0',END))
        txtMsg.delete('0.0',END)

    def cancelMsg():#取消消息
        txtMsg.delete('0.0',END)

    def sendMsgEvent(event):#发送消息事件
        if event.keysym == 'Up':
            sendMsg()

    #创建窗口
    t = Tk()
    t.title('与***聊天中')
   # t.

    #创建frame容器（实际上是将窗口划分成不同的功能区）
    frmLT = Frame(width = 500,height = 320,bg = 'white')
    frmLC = Frame(width = 500,height = 150,bg = 'white')
    frmLB = Frame(width = 500,height = 30)
    frmRT = Frame(width = 200,height = 500)

    #创建控件
    txtMsgList = Text(frmLT)#在父窗口frmLT中创建一个文本对象
    txtMsgList.tag_config('greencolor',foreground = '#008C00') #创建tag
    txtMsg = Text(frmLC)
    txtMsg.bind('<KeyPress-Up>',sendMsgEvent)
    btnSend = Button(frmLB,text = '发 送',width = 8,command = sendMsg)
    btnCancel = Button(frmLB,text = '取 消',width = 8,command = cancelMsg)
    imgInfo = PhotoImage(file = 'python.gif')
    lblImage = Label(frmRT,image = imgInfo)
    lblImage.image = imgInfo

    #窗口布局
    frmLT.grid(row = 0,column = 0,columnspan = 2,padx =1,pady = 3)
    frmLC.grid(row = 1,column = 0,columnspan = 2,padx =1,pady = 3)
    frmLB.grid(row = 2,column = 0,columnspan = 2)
    frmRT.grid(row = 0,column = 2,rowspan = 3,padx =2,pady = 3)

    #固定大小
    frmLT.grid_propagate(0)
    frmLC.grid_propagate(0)
    frmLB.grid_propagate(0)
    frmRT.grid_propagate(0)
'''
特别注意grid()函数:这个的几何管理器组织在父部件的表状结构中的部件。
 语法:
widget.grid( grid_options )
下面是可能的选项列表:
    column : 列放部件，默认为0（最左边的列）.
    columnspan: 部件占用多少列，默认为1.
    ipadx, ipady : 多少部件的像素，水平和垂直方向，部件的边界内.
    padx, pady : 多少部件的像素，水平和垂直方向，V的外边界.
    row: 该行放小部件;默认的第一行仍然是空的.
    rowspan : 多少行的部件占用;默认为1.
    sticky : 做什么，如果单元格是比小部件大。默认情况下，用粘=''，widget是在其细胞中心。粘可能是字符串连接的零个或多个N，E，S，W，东北，西北，东南，西南，罗盘方向指示部件坚持单元格的两侧和边角.
'''
    btnSend.grid(row = 3,column = 0)
    btnCancel.grid(row = 3,column = 1)
    lblImage.grid()
    txtMsgList.grid()
    txtMsg.grid()

    #主事件循环
    t.mainloop()


if __name__ == '__main__':
    main()

执行结果：
