Python tkinter不工作的按键符号（“输入”和“退出”）

我在tkinter上得到了坏的kysym进入和逃跑。enter的想法是，当用户按下enter键时，它会在python程序中创建一个新行，当用户按下escape键时，它会关闭程序。我的代码是否弄乱了什么

以下是错误：

Traceback (most recent call last):
  File "C:\Users\User\Desktop\python\turtle\helloworld.py", line 166, in <module>
    onkey(bye, "KP_Escape")
  File "<string>", line 1, in onkey

    self.tk.call(what + (sequence, cmd))
_tkinter.TclError: bad event type or keysym "KP_Escape"

而不是：

onkey(draw_newline, "KP_Enter")
onkey(bye, "KP_Escape")

做：

这个案子很重要。Turtle将在将这些键名发送到tkinter之前，用适当的Tk语法包装它们

onkey(draw_newline, "KP_Enter")
onkey(bye, "KP_Escape")

onkey(draw_newline, "Return")
onkey(bye, "Escape")
