Introduction to Python

Python is a prominent dynamic programming language that offers a rich assortment of GUI libraries, packages, and web frameworks, making it a versatile choice for developing efficient cross-platform applications. Python is particularly well-suited for rapid application development.

Hire Python Developers, Created in 1991 by Guido van Rossum, Python was initially designed as a general-purpose, high-level, and interpreted programming language with a focus on modularity and code readability. Over the course of its nearly 30-year history, Python has become one of the most widely used programming languages. Its simplicity and ease of understanding have contributed to its widespread adoption. Python is compatible with various operating systems such as Linux, Mac, Raspberry Pi, and Windows. It operates on an interpreter system, allowing code to be executed efficiently as soon as it is written. Python's development syntax is also known for its simplicity when compared to the syntax of other programming languages.

With a current popularity share of 31.73 percent among contemporary programming languages, Python's popularity continues to reach new heights.

Most-Used Languages by Developers

As per the latest developer survey by Stack Overflow, Python is the fourth most popular programming language 

The Python language is not only free and open source but also easy to learn, placing a strong emphasis on the DRY (Don't Repeat Yourself) principle and code readability. Thanks to its high-level nature, dynamic typing, and interpreted approach, Python simplifies error debugging and facilitates the swift creation of application prototypes. These qualities make Python a standout choice as a coding language.

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.
