The Definitive Guide to Python App Development – [Updated 2022]

Introduction to Python

Python is one of the top dynamic programming languages. It integrates a rich set of GUI libraries, packages, and web frameworks that allows developers to create efficient cross-platform applications. Python is a perfect language when it comes to rapid app development. 

Initially created in 1991 by Guido van Rossum, Python was released as a general-purpose, high-level, interpreted programming language with modularity and code readability as goals.

Throughout the course of its nearly 30 years of history, Python has grown to be one of the most widely used programming languages. It is quite a simple language that is easy to understand and learn. The language can run on several platforms like Linux, Mac, Raspberry Pi, Windows, etc. Python runs on an interpreter system which implies that code can be efficiently executed as soon as it is written. Python development syntax is also a lot simpler than the syntax of any other programming language.

With a current popularity share of 31.73 percent among contemporary development languages, Python’s popularity consistently achieves an all-time high.

Most-Used Languages by Developers

As per the latest developer survey by stack overflow , Python is the fourth most popular programming language 

Python language is free, open source and simple to learn and emphasizes on the DRY (Don’t Repeat Yourself) principle and readability. Being high-level, dynamically typed and interpreted, Python makes debugging of errors much simpler and allows rapid development of application prototypes, distinguishing itself as the language to code with. 

Can Python be used to build mobile applications?

Well, yes… It has become possible to build mobile applications in Python due to the release of the Kivy framework (Python tool) in 2011. 

It enables cross-platform development of the application for mobile devices and PC. Kivy framework makes use of a custom set of UI instruments that manage the same control elements on various platforms. 

Is it possible to build native mobile applications in Python?

Again the answer is yes. This is possible with another framework, BeeWare (another Python tool). 

BeeWare makes use of a set of instruments that manage the native control elements of all platforms. Here, checkboxes, buttons, and other elements provided by the system for which the app has been built will serve as UI controllers. Because of this, the product will appear completely native while being used on the platform it was built for. Thus, with the help of BeeWare framework, you can develop native mobile apps for iOS or for Android in Python.
