How to create a simple button in turtle, python, where if you click it, you can define it to print messages, or do other, more complex things.
Since the Python Turtle Graphics Module is built on top of Tkinter, a Tkinter button should work on a turtle screen
from turtle import Screen
from tkinter import *
screen = Screen()
screen.setup(width=600, height=400)
def do_something():
print("Good bye")
canvas = screen.getcanvas()
button = Button(canvas.master, text="Exit", command=do_something)
button.pack()
button.place(x=300, y=100) # place the button anywhere on the screen
screen.exitonclick()
