Python, being a powerful and flexible programming language, offers a variety of libraries that can come in handy for different tasks. One of these libraries is called Tkinter.
It’s a standard GUI (Graphical User Interface) kit for Python and allows us to create windows, labels, buttons, and more. In this tutorial, we are going to focus specifically on how to change the font in Python’s Tkinter.
Tkinter enables users to customize the text and labels they integrate into their GUI applications, offering changeable parameters like font family, font size, and font style. With advanced functionalities like Font class, you can further control your text’s appearance. Let’s get into the steps now.
Step 1: Import Tkinter and Font
First, we need to import the Tkinter and font packages:
|
1 2 |
from tkinter import * from tkinter import font |
Step 2: Creating the Window
After we’ve imported the necessary packages we need to create a Tkinter window:
|
1 |
root = Tk() |
Step 3: Define the Font
Now, we need to define the font family, size, and style. In the example below, we’re using the Arial font, size 20, and bold:
|
1 |
customFont = font.Font(family="Arial", size=20, weight="bold") |
Step 4: Applying the Font to Text
Then, we apply our defined font to a label and show it on the window:
|
1 2 |
label = Label(root, text="Hello World", font=customFont) label.pack() |
Step 5: Running the Application
Finally, we run the application:
|
1 |
root.mainloop() |
Full Code
This is the complete Python script that shows how to change fonts in Tkinter:
|
1 2 3 4 5 6 7 8 |
from tkinter import * from tkinter import font root = Tk() customFont = font.Font(family="Arial", size=20, weight="bold") label = Label(root, text="Hello World", font=customFont) label.pack() root.mainloop() |
The output window will display the text ‘Hello World’ in the defined Arial bold font with a size of 20.
Conclusion
In this tutorial, we learned how to change the font style, size, and family in Python’s Tkinter library. This might seem like a small detail, but customized text styles play a crucial role in improving the user experience and overall look of your GUI application. Keep exploring and experimenting with different parameters and settings to customize your application as per your needs.
