Which tkinter modules were renamed in Python 3?

Question

I am trying to create a file chooser dialog box. However, when I try to import tkMessageBox in Python 3, I get an error claiming that the module does not exist.

import tkMessageBox
# ImportError: No module named 'tkMessageBox' 

I get similar errors when trying to import other Tkinter modules in Python 3.

import Tkinter          # No module named 'Tkinter'
import tkColorChooser   # No module named 'tkColorChooser'
import tkFileDialog     # No module named 'tkFileDialog'

How do I import Tkinter modules in Python 3? What are the new module names?

Answer 1

The Tkinter package from Python 2 has been renamed to tkinter in Python 3, as well as other modules related to it.

Here is a list of renamed modules:

• Tkinter → tkinter
• tkMessageBox → tkinter.messagebox
• tkColorChooser → tkinter.colorchooser
• tkFileDialog → tkinter.filedialog
• tkCommonDialog → tkinter.commondialog
• tkSimpleDialog → tkinter.simpledialog
• tkFont → tkinter.font
• Tkdnd → tkinter.dnd
• ScrolledText → tkinter.scrolledtext
• Tix → tkinter.tix
• ttk → tkinter.ttk

I advise you to learn how to dynamically browse the modules with the dir command. If you are under windows, configure Python to use readline module to get auto-completion and make it much easier to list available classes in a module.

For a description of each module, refer to the official Python documentation. (Tkinter in Python 2.x, tkinter in Python 3.x)
