(Sorry for this indirect response due to technical reasons!)

The module "tkinter.messagebox" is an independent module within
the package "tkinter", so one needs to import it separately:

import tkinter.messagebox
tkinter.messagebox.showinfo( "Example" )

. If you want to hide the root window, add:

import tkinter
root = tkinter.Tk()
root.withdraw()
root.withdraw()

. To properly learn tkinter, however, ignore the messagebox module
during your first steps and start with:

import tkinter
root_window = tkinter.Tk()
root_window.mainloop()

as one of the most simple tkinter programs. Then add a label:

import tkinter
root_window = tkinter.Tk()
label = tkinter.Label( root_window, text="Hello!" )
label.pack()
root_window.mainloop()

. Read the part III "GUI Programming" in the book
"Programming Python" by Mark Lutz!

Do you have a file called tkinter.py in the current directory?

Is it possible that you've created a tkinter.py for your own tinkering?

This works for me. Hope it helps.

from tkinter import messagebox

messagebox.showerror("Hi", f"Hello World")

Dunno.

tkinter is a package, messagebox is a module within the tkinter package.
the messagebox module has some functions, such as showinfo(). You *can*
import those functions using "dot" expressions:

from tkinter.messagebox import showinfo

<function showinfo at 0x0000021CED0634C0>

You can also import the entire module using the "dot" syntax:

import tkinter.messagebox
messagebox.showinfo

<function showinfo at 0x0000021CED0634C0>

Whether you can directly ask for tkinter.messagebox depends on whether
it's been defined or imported in tkinter/__init__.py.

It's probably instructive that IDLE always brings it in this way.

Lib/idlelib/config_key.py:from tkinter import messagebox Lib/idlelib/configdialog.py:from tkinter import messagebox Lib/idlelib/editor.py:from tkinter import messagebox
... etc

It's a submodule of tkinter:

import tkinter.messagebox as mb
mb.showinfo

<function showinfo at 0x000001994C7F2020>
