Python小实例混合使用turtle和tkinter让小海龟互动起来(互动窗口)

Turtle 窗口

请看下图，turtle窗口图标是一片小叶子，估计它就是继承自 tkinter 库。

tkinter 窗口

参阅了一些资料，发现 turtle 方法可直接在 tkinter 的画布Canvas上操作：

源代码

  y = int(y.replace(')',''))

 except:
  x,y,R = 0,0,50  #输入错误则赋予默认值
 
 tu.goto(x,y-R)
 tu.pendown()
 tu.circle(R)

 tu.penup()
 tu.home()
 tu.clear()
 tu.speed(0)
 tu.color('red', 'yellow')
 tu.begin_fill()

  rad = int(rad)
