Python: 'Turtle' object has no attribute 'bye'

Question

I am trying to write turtle code where something is triggered and the turtle window closes, so I try to use turtle.bye() but I keep getting the error:

    Exception in Tkinter callback
Traceback (most recent call last):
  File "C:\Program Files\Python36\lib\tkinter\__init__.py", line 1699, in 
__call__
    return self.func(*args)
  File "C:\Program Files\Python36\lib\turtle.py", line 686, in eventfun
    fun()
  File "E:\Home made game\Chapter 1 Log Cabin.py", line 346, in k1
    player.bye()
AttributeError: 'Turtle' object has no attribute 'bye'

I just installed turtle and took a quick look. turtle.bye() and turtle.Screen().bye() don't work, but I never started a mainloop. Are you sure you started a turtle mainloop()? — GaryMBloom

bye() is a method of the Screen singleton instance, not Turtle. It is also mapped to a top level function in the turtle package. It will not work with a Turtle instance. You can invoke it several ways:

import turtle

turtle.Screen().bye()  # not a turtle instance, the turtle package

turtle.bye()  # not a turtle instance, the turtle package

turtle.getscreen().bye()  # not a turtle instance, the turtle package

yertle = turtle.Turtle()
yertle.getscreen().bye()  # turtle instance gets screen singleton to invoke bye()

Once you call bye() the turtle world shuts down in a manner that's not meant to be restarted.
