In this lesson we want to learn that Is Kivy Python good, also we will talk about installation proccess of kivy and a simple example with Python Kivy.
What is Python Kivy ?
Kivy is popular open source Python library for developing cross platform user interfaces. It is good for creating multi touch applications and games, and it has different builtin widgets and layouts that can be easily customized. Many developers consider Kivy to be good choice for developing mobile apps, and it is also used in the development of desktop applications. However, it is worth considering that it is not as popular as other frameworks and libraries, like PyQt and Tkinter, and you may find fewer resources or community support.
What Applications are Using Kivy ?
Kivy is used to develop different types of applications, including:
- Mobile apps: Kivy’s ability to create multitouch interfaces and it makess it good choice for developing mobile apps. many developers use Kivy to create apps for Android and iOS.
- Games: Kivy’s built-in support for 2D graphics, animations and input handling and it makes it good choice for game development.
- Desktop applications: Kivy’s ability to create cross platform user interfaces makes it well suited for developing desktop applications.
- Educational apps: Kivy’s ease of use and wide range of built in widgets makes it good choice for developing educational apps for children.
- Scientific and engineering applications: Kivy’s ability to create multitouch interfaces and support for 2D graphics and it makes it well suited for developing scientific and engineering applications.
- Interactive installations and exhibits: Kivy’s ability to create multi touch interfaces and support for 2D graphics and it makes it good for developing interactive installations and exhibits.
It’s worth mentioning that Kivy is relatively new framework and its use is not as widespread as other frameworks.
Is it Good to Use Kivy for Mobile Apps ?
Kivy is popular choice for developing mobile apps due to its ability to create multi touch interfaces and support for different platforms, including Android and iOS. it also has builtin support for 2D graphics and animations, which can be useful for creating visually appealing apps. also it has different builtin widgets and layouts that can be easily customized to create professional looking user interface.
However, it’s worth considering that Kivy is not as widely used as other mobile app development frameworks, such as React Native or Flutter, so you may find fewer resources or community support. also it may not be the best choice for developing apps that require a lot of processing power or complex 3D graphics, as the framework is primarily focused on 2D graphics.
In result we can say that Kivy is good choice for developing mobile apps, especially if you are looking for Python based framework that is easy to use and has built in support for multi touch interfaces and 2D graphics. but it’s important to consider the specific needs of your app and the resources available to you before making a decision.
How to Install Kivy ?
Installing Kivy has different steps than installing regular Python package, because it requires installing some additional dependencies.these are the steps to install Kivy on different platforms:
Windows:
- Install Python. ou can download latest version of Python from official website (https://www.python.org/downloads/).
- Install the dependencies. Kivy requires several dependencies including Microsoft Visual C++ Build Tools which you can download from Microsoft website (https://visualstudio.microsoft.com/downloads/).
- Install Kivy. after that you have installed Python and the dependencies, you can use pip to install Kivy:
1 |
pip install kivy |
macOS:
- Install Python. You can download the latest version of Python from official website (https://www.python.org/downloads/).
- Install the dependencies. Kivy requires several dependencies which you can install using Homebrew:
1 |
brew install pkg-config sdl2 sdl2_image sdl2_ttf sdl2_mixer gstreamer |
Install Kivy. after that you have installed Python and the dependencies, you can use pip to install Kivy:
1 |
pip install kivy |
Linux:
- Install Python. you can download latest version of Python from the official website (https://www.python.org/downloads/).
- Install the dependencies. Kivy requires several dependencies, which you can install using your package manager for example on Ubuntu you can use this :
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 |
sudo apt-get install -y \ python3-pip \ build-essential \ git \ python3 \ python3-dev \ ffpyplayer \ libsdl2-dev \ libsdl2-image-dev \ libsdl2-mixer-dev \ libsdl2-ttf-dev \ libportmidi-dev \ libswscale-dev \ libavformat-dev \ libavcodec-dev \ zlib1g-dev |
Install Kivy. after that you have installed Python and the dependencies, you can use pip to install Kivy:
1 |
pip3 install kivy |
Please note that the above instructions are general and may be different depending on your specific system configuration. It’s always a good idea to check the official documentation for the most up to date and accurate installation instructions.
Basic Example of Kivy
1 2 3 4 5 6 7 8 9 |
from kivy.app import App from kivy.uix.button import Button class MyApp(App): def build(self): return Button(text='Hello, Kivy - GeeksCoders!') if __name__ == '__main__': MyApp().run() |
This code creates a Kivy app that displays button with the text “Hello, Kivy – GeeksCoders!” when run. App class is the base class for creating Kivy app and the build method is used to specify the root widget that will be displayed when the app runs. In this case, the root widget is a button.
This is breakdown of the code:
from kivy.app import App line imports the App class from the kivy.app module.
from kivy.uix.button import Button line imports the Button class from kivy.uix.button module.
class MyApp(App): line defines a new class called MyApp that inherits from the App class.
def build(self): line defines the build method that specifies the root widget that will be displayed when the app runs.
return Button(text=’Hello, Kivy – GeeksCoders!’) line creates a new button widget with the text “Hello, Kivy!” and returns it as the root widget.
if __name__ == ‘__main__’: line is used to run the app when the script is executed.
MyApp().run() line creates a new instance of the MyApp class and calls its run method to start the app.
When you run this code, it will open window with button that says “Hello, Kivy – GeeksCoders!” and you can interact with it.
This is just a basic example of how to create simple Kivy app. You can use the many widgets and layouts provided by Kivy to create more complex and professional user interfaces.
