Looking for the best Python GUI frameworks? Check out our list of the top 8 options for building intuitive and attractive graphical user interfaces in Python.
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. And even though the language is very beginner-friendly, that doesn't mean it's limited in what you can do. As you begin your journey with this language, you will find that creating text-based applications is extremely easy. With two simple lines of code, you can create the popular Hello, World! application. This code looks like this:
# This program prints Hello, world! print('Hello, world!') Run the program, and it would print out: Hello world!
Although this is very simple, you can create quite complex text-based Python applications. For some, though, text-based apps aren't exactly the best option. This is especially true when these applications will be used by people (clients, consumers, customers) who are not exactly used to using non-GUI applications.
Fortunately, it is possible to create GUI applications with Python. Let's continue with Hello, World! application. Using a GUI framework, you can create the graphical version of Hello, World! equal to:
# Python tkinter hello world program from tkinter import * root = Tk a = Label(root, text ="Hello World") a.pack root.mainloop
The important thing to note above is the use of tkinter, which is a library for Python that makes it possible to create user interfaces and complete GUI applications. There are quite a few libraries for the language, and because it is so popular, you should have no problem finding a Python development company to help you create a well-designed GUI application for your company.
Why is it important to choose the right GUI framework for Python?
As you probably expect, you can't make GUI development in Python easier without making use of one of the many GUI frameworks. However, you can't just pick any random Python GUI framework. For example, some frameworks can only be used with specific operating systems. Other Python GUI frameworks are not independent and depend on other GUI frameworks. Additionally, some Python GUI frameworks can be used to create only specific types of GUIs or certain aspects of a GUI.
Because of these issues, it's important to choose the right framework for your Python GUI project.
Fortunately, there are many frameworks to choose from, and some of them support cross-platform applications and can take care of all your GUI needs.
Let's take a look at some of the best options on the market.
Things to Consider When Choosing a Python Graphical User Interface
As mentioned earlier, there are certain things you should consider when choosing a Python GUI framework. These considerations include the following.
- Operating system specific: If your application is only native to a specific operating system, rather than multiple platforms, you must make sure that the library you choose supports that operating system. If you plan to release your application to multiple platforms, you will want to make sure the library supports all target operating systems.
- GUI needs: If you know the necessary elements of your GUI (such as clickable buttons, drop-down menus, forms, windows, and other controls), you should know whether the GUI framework is capable of designing and controlling these elements.
- Support for multiple versions: Although Python 2 has reached the end of its useful life, there are still people and companies using it. When selecting a GUI framework, make sure it is compatible with the version of Python you use.
- Extension support: You may be using multiple extensions for your application (such as OpenGL or GTK). In this case, make sure the GUI library you choose supports these extensions.
- Support: Does the framework you selected have a thriving community of Python developers? If not, you might consider a different GUI, as help may be difficult to find and the framework itself may not be around for long.
Now that you understand what a Python GUI framework is and what to consider when making your selection, let's look at some of the best frameworks available.
Top 8 Python GUI Packages and Libraries
Although you can find a large number of popular Python GUI frameworks, not all of them are equally viable options. The eight you see below have all been reviewed and deserve your consideration.
PyQT5
PyQT5 is probably one of the most popular Python GUI frameworks on the market. Built around the PyQT package, this framework makes it easy to create all types of applications for virtually any platform. PyQT5 supports Android, iOS, Linux, macOS and Windows.
What makes PyQT5 stand out is its use of QtGUI and QtDesigner, which provide a drag-and-drop means of implementing visual elements for your GUI applications. Even better, if your Python developers prefer to program these elements through code, they have that option too.
Key Features // Product Highlights
- More than 600 classes covering a wide range of needs.
- Supports versions 4.x and 5.x of the Qt framework.
- Supports SQL databases.
- Supports web toolkits for building web applications.

Tkinter
Tkinter comes pre-installed with Python, so there is no need to install anything else to create a GUI application. And like Python itself, Tkinter is very easy to learn and use. For these two reasons, Tkinter is the best GUI library for those new to Python.
Each Tkinter widget includes a different level of customization, meaning some widgets have few customizations while others offer a lot. You'll find widgets for frames, buttons, check buttons, labels, file dialogs, and screens.
Tkinter is an open source library and offers a syntax that is very much in line with the simplicity of Python code.
Key Features // Product Highlights
- Requires zero dependencies.
- Portable, so you can create graphical user interfaces for almost any operating system.
- Python scripts using Tkinter do not need to be modified when migrating from one platform to another.
- Easily themeable.
PROS | CONS |
Easy to learn and use. | Limited in what you can do. |
Flexible. | Best used for very simple GUI applications. |

Very user-friendly syntax. | A little slower (due to the layered approach) than other libraries. |
PyGUI
Just like PyQT5, PyGUI must be installed separately from Python. To install PyGUI, you must use the pip installer (which is included with Python). On the other hand, however, this is a lightweight API, so very little code is required to connect the application to the hosting platform. Although PyQUI does not support mobile applications, it can be used to create GUIs for Linux, macOS, UNIX, and Windows.
PyGUI also supports numerous Python extensions such as OpenGL and GTK. With PyGUI, you can create GUI elements such as buttons, radio buttons, and menus.
Key Features // Product Highlights
