Create a new window using GTK and Python in Ubuntu and Ubuntu based distributions

The tutorial presumes you already have Python3 installed on your system. If you don't please visit my other tutorial, How to create a basic Python3 script in Ubuntu and Ubuntu based distributions

I have always wanted to learn how to create an application in Ubuntu or an Ubuntu based distribution. There is a lot of information out there and If I'm honest it can get quite confusing.

I also don't mind admitting that I am no expert in this field, but I wanted to put something down that I could revisit later to give me a starting point. Please note if your using Kubuntu / KDE things will be different.

In this tutorial, we create a basic window using Python3 and GTK.

First of all you need to make sure python 3 is installed, most Ubuntu and Ubuntu and Ubuntu based distributions already include this, but to check enter the following command in the terminal.

python3 --version

If you don't get any ouput from the terminal enter the following command in the terminal

sudo apt-get install python3

Once installed let's create our first window

Create a new file on your Desktop name new_window.py
Next enter the following command in the terminal to get your path to python3

which python3

Create a new file on your desktop, and save this as new_window.py, then copy and paste the code below.

#!/usr/bin/python3

import gi
gi.require_version("Gtk", "3.0")
from gi.repository import Gtk

window = Gtk.Window(title="Hello World")
window.show()
window.connect("destroy", Gtk.main_quit)
Gtk.main()

Next we need to make the script executable, so enter the following command

chmod +x new_window.py

Then enter the following in the terminal

./new_window.py

If everthing works correctly a new window should pop up.
