Python tkinter label

What is label widget in tkinter

The tkinter is a Python library for creating GUI-based applications.

• The label is one of the available widgets in tkinter like buttons, entry, etc.
• Label widget is a box where you may place text or image.
• Generally, this is used as an information box explaining the purpose of another widget.
• For example, we have an entry widget (single-line textbox) in the form to enter name.
• To inform the users purpose of that entry widget, you may use a label beside the textbox.

The section below shows using the label widget with various available options.

A simple label example

In this example, we created a window and placed a label in it. No other widget is created. Have a look:

Code:

Creating labels with background and foreground colors

By using bg option, you may create a label with a background color. Similarly, the text color of the label can be set by the foreground color option i.e. fg.

See a program with a green background and white foreground color label below:

A label with a textbox/entry example

In the example below, we create a label along with a textbox/entry widget to show the purpose of the textbox.

Code:

Using an image in label example

Rather than text, you may also use image in the label. For that, use the image option. First, have a look at an example below and then we will explain how it worked.

Code:

How did it work?

Step 1:

Consider this line:

from PIL import Image, ImageTk

We used Pillow Image Library to read and convert images to Python objects, so we can display them.

In order to install PIL, execute this command in the CMD (if you don’t already have):

pip install pillow

 Step 2:

Then we specified the image in this line:

img = ImageTk.PhotoImage(Image.open(“E:/logo.png”))

Set the path according to your system.

Step 3:

Using image option in the label:

lbl_img = tk.Label(win, image = img)

An example of padding options

You may add extra space to the left, right, top, and bottom of the text by using the padding options of the label widget.

For adding padding to the left and right of the text, use padx option.

To add space in the top and bottom, use the pady option.

Code:

Changing the font size and name of the label example

In the example below, we created various-sized labels by using the font option of the label widget. Besides, font names are also given for two labels Verdana and Arial.

Code:
