8 Best Python GUI Frameworks

One of the best things about Python is how easy it is to learn. Of all the programming languages on the market, none is as simple as Python. Even though the language is very beginner-friendly, that doesn’t mean your capabilities are limited. When you first start your journey with this language, you’ll find that creating text-based applications is remarkably easy. With two simple lines of code, you can create the popular Hello, World! application. That code looks like this:

# This program prints Hello, world!
print('Hello, world!')
Run the program, and it would print out:
Hello, world!

Although that is overly simple, you can create fairly complex text-based Python applications. For some, however, text-based applications aren’t exactly the best option. This is especially so when those applications will be used by people (clients, consumers, customers) who aren’t exactly accustomed to using non-GUI applications.

Thankfully, it is possible to create GUI applications with Python. Let’s keep with the Hello, World! application. Using a GUI framework, you can create the graphical version of Hello, World! like so:

# Python tkinter hello world program
from tkinter import *  
root = Tk()
a = Label(root, text ="Hello World")
a.pack()
root.mainloop()

The important thing to notice above is the use of tkinter, which is a library for Python that makes it possible to create user interfaces and full-fledged GUI applications. There are quite a few libraries for the language. Because it’s so popular, you shouldn’t have any problem finding a Python development company to help you create a well-designed GUI application for your company.

Why Is Choosing the Right GUI Library for Python Important?

You cannot facilitate Python GUI development without using one of the many GUI libraries. However, you can’t just choose any random Python GUI framework. For example, some frameworks can only be used with specific operating systems. Other Python GUI frameworks aren’t stand-alone and depend on other GUI frameworks. Moreover, some Python GUI frameworks can create only specific types of GUIs or certain aspects of a GUI.

Because of these issues, choosing the right framework for your Python GUI project is important.

Fortunately, there are plenty of frameworks to choose from. Some of them support cross-platform applications and can take care of all your GUI needs.

Things to Consider When Choosing a Python Graphical User Interface

As mentioned previously, there are certain things you must consider when choosing a Python GUI framework. Such considerations include the following.

1. OS-specific: If your application will be native to a specific operating system only, as opposed to multiple platforms, you must make sure the library you choose supports that OS. If you plan to release your application to multiple platforms, you’ll want to know that the library supports all targeted OSs.
2. GUI needs: If you know the necessary elements of your GUI (such as clickable buttons, drop-downs, forms, windows, and other controls), you must know if the GUI framework is capable of drawing and controlling those elements.
3. Support for multiple versions: Although Python 2 has reached end of life, there are still people and companies using it. When selecting a GUI framework, make sure it supports the version of Python that you use.
4. Extension support: You might use multiple extensions for your application (such as OpenGL or GTK). If so, make sure the GUI library you choose supports those extensions.
5. Support: Does your selected framework have a thriving community of Python developers? If not, consider a different GUI, as help could be hard to come by, and the framework may not be around for long.

Now that you understand a Python GUI framework and what to consider when selecting, let’s examine some of the best frameworks available.
