How to create user interface via Python?

In this article, we will learn how to create a user interface using python.

What is a graphical user interface?

Terminology "Graphical User Interface" (or "GUI" ) refers to a set of visual element items that can be interacted with in computer software to display information and interact. In response to human input, objects may change appearance characteristics such as color, size, and visibility. Graphical components such as icons, cursors, and buttons can be enhanced with audio or visual effects (such as transparency) to create graphical user interfaces (GUIs).

If you want more people to use your platform, you need to make sure it has a good user interface. This is because the combination of these factors can greatly affect the quality of service provided by your app or website.

Python is widely used by developers as it provides various frameworks for building graphical user interfaces. Due to the interactive nature of Python, creating GUI frameworks is a piece of cake. GUI frameworks available in Python range from cross-platform to platform-specific.

The Python GUI framework contains many features that may be difficult for developers with intermediate or beginning skills, but learning them is simple. Python is the most widely used language on StackOverflow, and its rich development options have piqued the interest of programmers around the world. Problems can arise if they start going crazy while developing a program. In doing so, they must find the right balance between performance, security, and speed; doing so will help them create applications that are more user-friendly and focused on their needs, while also being powerful, user-friendly, and smooth user interface.

Here are the best Python libraries for Graphical User Interface (GUI) -

PyGUI

PyGUI, the abbreviation of Python Graphical User Interface Project, is such a framework. Developers can use PyGUI's plug-in capabilities to create applications with special Python capabilities, which allows them to write less code between the application and the basic resources of this Python GUI platform. This GUI project is cross-platform, so you can use it with Windows, Unix, or the latest macOS software.

In fact, the documentation of this lightweight framework is organized in such a way that developers and other programmers can simply design and develop UI (User Interface) without having to constantly refer to other GUI frameworks. PyGUI is compatible with Python 2 and 3 and can be easily installed.

despair

Kivy is one of the most popular cross-platform development frameworks. Kivy allows you to create applications using Python for Android, iOS, Linux, Windows, and various other web applications.

This library is built on Python and Cython. It has superior multi-touch capabilities, taking full advantage of the full power of your device screen for input.

It also supports gestures and other types of input, making it an excellent choice for designing modern applications.

Kivy is a visual programming language that combines node-based and GUIM-based programming parts. These features help make the library more adaptable and efficient.

However, it may fall short when it comes to creating intuitive, complex GUIs. Kivy is open source free software licensed under the MIT license.

Before installing Kivy, you must first complete some prerequisites, such as updating Python and installing pip. Please enter the following code -

pip install --upgrade pip setuptools virtualenv

Next, set up a virtual environment to test and install Kivy and its dependencies. You can create a virtual environment by doing the following: kivy_venv -

python -m virtualenv kivy_venv

Use the activate command to activate the virtual environment -

source ./kivy_venv/bin/activate

Finally, after activating the virtual environment, use the kivy[base] command to install Kivy. This will install minimal dependencies as well as a basic GUI software installation.

pip install "kivy[base]"

Tkinter

Tkinter has attracted a large community of Python programmers eager to help shape Tk into a GUI toolkit. What does this toolbox contain? The program provides a basic set of GUI Widgets that can be used to create lightweight, free, and accessible UIs. This highly configurable GUI widget includes -

• Button is used to obtain user input.

• Checkboxes are used to group things like colors, black and white images, and border sizes.

• File Dialog Lets you send files to and from the application.

• TagDisplays information in text form.

• CanvasAllows developers to create charts and graphs by drawing.

• Framework provides great flexibility in structuring your application.

To make a desktop or Python GUI application, all you have to do now is browse the TKinter documentation and learn how to use its many GUI features.

PyQt5

One of the most commonly used Python GUI frameworks is PyQt5, which is developed by RiverbankComputing. The PyQt package is based on the Qt framework, which is used to build applications that can run on many different platforms.

PyQt5 适用于所有平台，因此程序员可以使用它来制作适用于 Mac、Windows、Linux、iOS 和 Android 的应用程序。它配备了 QtGUI 和 QtDesigner 模块，为开发人员提供了可以拖放使用的视觉元素。您还可以选择使用代码来制作元素，这样可以轻松制作小型和大型应用程序。

以下是 PyQt5 的一些优点 -

• 编码适应性（多功能性）

• 各种 UI 元素

• 大量学习资源

• 用于网络、数据库管理和其他目的的各种本机平台 API。

PySimpleGUI

PySimpleGUI 是 Tkinter、Qt 和 WxPython GUI 框架的包装器。它将它们转换为简单且一致的 API。

这个想法是让个人可以轻松地设计 GUI，而无需掌握各种 API 的所有复杂性。它缩短了 API 的学习曲线，使您能够专注于代码的逻辑。

它通过提供在所有 GUI API 中保持一致的一致 API 来实现这一切。

使用以下代码安装 PySimpleGUI -

pip install PySimpleGUI

结论

作为一种开源语言，Python 提供了一系列替代方案来满足各种开发需求。

这些是市场上一些最流行、最有效的 Python GUI 框架。这些框架使程序员能够简单、安全地构建 GUI 界面。您可以根据自己的需求选择最适合您的Python GUI框架。
