1. Labels in Tkinter

Hello Tkinter Label

We will start our tutorial with one of the easiest widgets of Tk (Tkinter), i.e. a label. A Label is a Tkinter Widget class, which is used to display text or an image. The label is a widget that the user just views but not interact with.

There is hardly any book or introduction into a programming language, which doesn't start with the "Hello World" example. We will draw on tradition but will slightly modify the output to "Hello Tkinter" instead of "Hello World".

The following Python script uses Tkinter to create a window with the text "Hello Tkinter". You can use the Python interpretor to type this script line after line, or you can save it in a file, for example, "hello.py":

import tkinter as tk

# if you are still working under a Python 2 version, 
# comment out the previous line and uncomment the following line
# import Tkinter as tk

root = tk.Tk()

w = tk.Label(root, text="Hello Tkinter!")
w.pack()

root.mainloop()

Starting our example

If we save the script under the name hello.py, we can start it like this using the command shell:

$ python3 hello.py

If you run the command under the Gnome and Linux, the window the window will look like this:
