Python App Development

Technology is improving a lot day by day. Hence, leading to gradual upgrades in Smartphones, Artificial Intelligence, Supercomputers, etc. Then, to use these technologies, we developed various programs and mobile applications that are worked by programming languages. One such popular language is Python. 

Python programming language is prevalent among developers. It was declared as the top programming language of 2019, beating the original coding language – Java. It has facilitated the whole mobile app development process to a great extent and won the title mentioned above.

So, let’s look at Python app development and the kind of apps it can build.

Why is Python so Popular?

Python has become very popular, and one of the most preferred languages for developers. We will have a look at why:


Here, the programs are added to the interpreter and are run directly. It means there is no compiling, which usually happens for almost all the other languages. It’s quick and easy to get your hands on the Python code’s feedback, such as recognizing errors. You can finish and execute your programs faster than other programming languages.

Easy to Read and Understand

One of the significant features of Python is its syntax. The rules of its syntax let the developers express concepts without writing any additional code. It has a way of making complicated things simple; hence it is suitable for beginners to learn.

Python is the only language that focuses on code readability and allows developers to use English keywords instead of punctuation marks. Such factors make Python perfect for mobile applications and custom applications. Plus, the exact codebase helps developers to maintain and update the software without any extra effort. 

Facilitates Test-Driven Development 

Python makes prototype creation for software applications easier. It fully supports prototype development and allows you to build applications directly from the prototypes by refactoring them. Coding and testing go hand-in-hand now. Python has adopted the methodology called TDD, acronymous of test-driven development.


Python supports many operating systems, like Android, iOS, and Windows. You can use Python interpreters to run and use the code across tools and platforms. Python also lets you run the same code across multiple platforms and the modified app code without any recompilation. Plus, if you want to check the impact of changes made in the code, even if instantly, then you can choose Python.

Strong Standard Library

Python has a robust standard library that gives it an edge over other languages. It enables you to select modules from a wide range as per the requirements. Python’s module lets you add functionalities later in the process without extra coding.

Most Demanding Python Frameworks for App Development 

The most popular and demanding Python Frameworks in the app development industry are as follows:

Kivy vs BeeWare

Custom mobile app development for Android and iOS was not Python’s strong suit in the past – but things are different today. In earlier times, Python did not have a strong story for writing GUI for mobile apps. Android and iOS mobile app development were pretty out of the question with only Python. 

There have been many Python Development changes in recent years that enhanced Python’s outlook for writing codes for mobile apps. Let’s have a look at some latest options for custom mobile app development using Python. There are mainly two frameworks to call out specifically: the BeeWare project and Kivy. 

BeeWare Project – Native Python Mobile Apps

BeeWare is the second graphical UI and mobile app development framework. It provides you with useful tools and an abstract layer that you can use to write original-looking desktop and mobile apps using Python. One of the critical differences between BeeWare and Kivy is that BeeWare programs make use of the native UI toolkit for all the platforms. On the other hand, Kivy uses a custom user interface toolkit that uses the same kind of controls on all the platforms.

In the BeeWare tool, the widgets that control your mobile app are checkboxes, buttons, and form elements provided by the base operating system. So, you can create mobile apps that feel and look 100% original on each mobile (and desktop) platform.

One of the major drawbacks in using this tool is that the BeeWare project is relatively new and is presently led by Pythonista Russel Keith-Magee, a development leader. As with other frameworks that have not yet had the opportunity to mature for years would mean more work for you as a mobile app development company due to lack of features, API changes, and errors. 

Kivy – Cross-Platform Python GUIs

Kivy is an open-source library of Python for creating GUI for mobile apps across various platforms. It enables developers to develop pure graphical Python apps that run on major platforms (Linux, macOS, Windows) and iOS and Android. 

Whenever you hear about a new toolkit of the graphical user interface, you would want to know how it feels “authentic.” The big graphic user interface app should play with the strengths of that particular platform that it runs on. For example, you would expect consistency among the mobile apps you use when you use an iPhone. It is a big concern to use a mobile app designed with user interface styles from another platform.

Kivy has a customized user interface toolkit that offers its versions of text stickers, text entry forms, and buttons, to name a few. So, the tools are not represented using the native user interface controls. It has its pros and cons. On the other hand, the tool ensures your mobile application’s applicability and consistency from one platform to another. Plus, the Android mobile app will not sound or look like an Android mobile app. 

Depending on the type of mobile app you consider, it isn’t a problem at all. For example, the “cradle” of the user interface is not crucial. The same would apply to different types of specialized mobile apps like MIDI graphics controllers to control music. But for other mobile apps, it has a great impact on usability.

To work with a non-native UI toolkit in mobile apps, Kivy is a fantastic choice for you. The tool allows you to create mobile apps using your Python skills without learning another platform language such as Apple Swift.
