How To Install Tkinter In Windows

Tkinter is the de facto way in Python to create Graphical User Interfaces (GUIs). Installing Tkinter on Windows is as simple as installing Python 3.x since Tkinter is included in the Python 3 core. 

However, if you want to take advantage of the latest version of Tkinter, you’ll need to install a version of Python that supports Tcl/Tk 8.5 or greater, as well as Ttk (Tile extension integrated into Tk), which is required in order to run the current Tk widget set. 

• Python 3.7 or greater for Windows comes with everything you need to run Tk fully configured out-of-the-box. 
• If you have Python 3.6 or an earlier version, you can simply upgrade to a newer Python version that includes the latest version of Tkinter. 

Python Distributions with Tkinter

Popular Python distributions like ActivePython and Anaconda both come with Tkinter.

The simplest method to install Tkinter in a Windows environment is to download and install ActivePython 3.8 from here.

Alternatively, you can create and activate a Conda environment with Python 3.7 or greater that is integrated with the latest version of Tkinter. 

1. To create a new Conda Python environment named <env_name> and install python 3.8, open an Anaconda Prompt or terminal and enter:

$ conda create --name <env_name> python=3.8

2. To activate the new environment that has Python 3.8, and switch to it, enter:

$ activate <env_name>

Verify Tkinter Installation

To verify whether Tkinter is installed ready to be loaded by Python, run the following code in a Python console:

>>> import tkinter
>>> tkinter._test()

If Tkinter is installed and working correctly, a small popup window will appear. The first line at the top of the window should state, This is Tcl/Tk version 8.6.

Watch video demonstration here.

You can also verify the Tcl/Tk version used by Tkinter with the following code:

>>> import tkinter

>>> tkinter.Tcl().eval('info patchlevel')

The output should be similar to:

>>> '8.6.9'

You can also run a test script to make sure that Tkinter is functioning correctly. For example:

>>> from tkinter import * 

>>> root = Tk() 

>>> test = Label(root, text="<message>") 
>>> test.pack() 

>>> root.mainloop() 

If Tkinter is correctly installed, a small popup window displaying a message should appear.
