Python turtle works with tkinter. How to get the root you know from tkinter? Like this:

import tkinter
root = tkinter.Tk()

but for turtle.

The top-level widget is available through the winfo_toplevel method of the turtle canvas:

import turtle

canvas = turtle.getcanvas()
root = canvas.winfo_toplevel()

It is of a subtype of Tk:

import tkinter

assert type(root) is turtle._Root
assert isinstance(root, tkinter.Tk)

    Thanks for correcting me! Very interesting that there are people with 5k rep using turtle / having knowledge using it. – palsch Jun 02 '18 at 14:54
  • Actually, I found your question while researching for [this answer](https://stackoverflow.com/a/50657029/674064). :-) That's also how I noticed your answer was wrong: I couldn't call `turtle.getcanvas().protocol()` – das-g Jun 02 '18 at 17:06

As pointed out by @das-g

root = turtle.getcanvas().winfo_toplevel()

gives you an object representing the turtle root window.

However, if your use case is to integrate turtle graphics with a full-blown Tkinter application, the explicit approach should be preferred at all times:

from tkinter import *
import turtle

root = Tk()
turtle_canvas = turtle.Canvas(root)
turtle_canvas.pack(fill=BOTH, expand=True) # fill the entire window

protagonist = turtle.RawTurtle(turtle_canvas)
protagonist.fd(100) # etc.

This adds the extra benefit of being able to control position and size of the turtle canvas. Plus, having explicit code helps others understanding it.

turtle.getcanvas()

returns the object you are (I am) looking for.

  • That returns the canvas, which _isn't_ the top-level widget: `assert not isinstance(turtle.getcanvas(), tkinter.Tk)`. – das-g Jun 02 '18 at 12:11
