Installing tkinter in Linux Environment

tkinter is a set of controls described in the python programming language to build a graphical user interface (GUI). Therefore, before learning tkinter installation, you need to make sure that you have installed Python correctly.

You can directly install Python 3 and tkinter using the following command.

sudo apt-get install python3       # Installing Python 3
sudo apt-get install python3-tk    # Installing tkinter

Installing Python 3

This tutorial takes python 3 as the target language and directly inputs python or python 3 on the Linux terminal. If the following contents are output, it proves that you have correctly installed python 3.

ubuntu:~$ python
Python 3.8.10 (default, Jun  2 2021, 10:49:15)
[GCC 9.4.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>>

If you output the following, it means that you have installed Python 2. You can try entering Python 3 to start Python 3.

ubuntu:~$ python
Python 2.7.17 (default, Feb 27 2021, 15:10:58)
[GCC 7.5.0] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>>

If you input Python 3 and the terminal outputs something similar to the following, then you have not installed Python 3.

ubuntu:~$ python3

Command 'python3' not found, but can be installed with:

sudo apt install python3

You can install Python 3 using the following command:

sudo apt-get install python3

Installing pip3

pip is a Python package management tool. You can use it to install and uninstall packages. You usually need to install pip before learning Python.

pip2 is the package management tool of Python 2, and pip3 is the package management tool.

If you input the pip --version command and output the following contents, it proves that you have not installed pip.

ubuntu:~$ pip --version

Command 'pip' not found, but can be installed with:

sudo apt install python3-pip

You can install pip3 using the following instructions:

sudo apt-get intall python3-pip

Before installing pip, be sure to install python3 correctly.

If you enter the pip --version command and output the following, congratulations on successfully installing pip3.

ubuntu:~$ pip --version
pip 20.0.2 from /usr/lib/python3/dist-packages/pip (python 3.8)

After pip3 is installed for the first time, it usually needs to be updated. Please use the following command:

pip3 install --upgrade pip

So far, both Python 3 and pip3 have been successfully installed on your computer.

Installing tkinter

If you enter import tkinter in the python 3 environment and press enter to output the following content, it indicates that you have not installed tkinter.

ubuntu:~$ python3
Python 3.8.10 (default, Sep 28 2021, 16:10:42)
[GCC 9.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import tkinter
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'tkinter'
>>>

At this point, you need to use the following command to install tkinter:

sudo apt-get install python3-tk

If you output the following in the python 3 environment, congratulations on successfully installing tkinter:

ubuntu:~$ python3
Python 3.8.10 (default, Sep 28 2021, 16:10:42)
[GCC 9.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import tkinter
>>>

A simple tkinter test program

To make sure everything works, let's try running a "Hello World" program in tkinter. For such short content, you can input it directly into the interpreter instead of putting it into a file using your favorite text editor.

from tkinter import *
from tkinter import ttk
root = Tk()
ttk.Button(root, text="Hello World").grid()
root.mainloop()

After the above code is executed, a window as shown in the following figure will pop up:

The code in this article is executed under wsl ubuntu, so the window belongs to Windows style. If you execute this code in other environments, it may be slightly different and will not affect your learning.
