Web development, programming languages, Software testing & others

Is Python Open Source?

Yes, Python is an open source language, which means it is free and available for everybody to use for any purpose. The python software foundation manages the python language. It is developed under an OSI-approved open source license, making it freely available, usable, and distributable.

The Open Source Initiative (OSI) is a California public benefit corporation with 501(c)3 tax-exempt status, founded in 1998. Guido van Rossum developed Python in the late eighties and early nineties at the National Research Institute for Mathematics and Computer Science in the Netherlands.

Refer to the below link for more information about Python History and License.

Features of Python Open Source Language

Interpreted:

Python is processed at runtime by the interpreter. No need to compile the program before executing it.

Interactive:

Python can run in an interactive mode, i.e., the program can be written in a command line shell that gives immediate output for each statement.

Cross-platform Language:

Python works on different platforms like Windows, Linux, Mac, etc.

Ease to Learn:

Python is easy to learn and easy to use; it is developer friendly.

Expressive: Python is easy to read and understand. The syntax of python is like English statements.

The large set of Libraries:

Python provides a large set of libraries, modules, and functions that enable the rapid development of applications.

GUI Support:

Python supports the development of a Graphical User Interface

Integrated:

Python can be easily integrated with other languages like Java, C/C++, etc.

Databases:

Python provides interfaces for a large set of databases.

Free and open source:

Python is freely available on the official website. Anybody can use it, modify re-distribute it. But the Python language is copyrighted.

Object-Oriented:

Python supports Object Oriented style of programming that encapsulates code within the object.

Datatypes:

Python has various basic data types like integer, floating point numbers, String (both in ASCII and Unicode), lists, dictionaries, etc.

Modules and Packages:

Code can be grouped into packages and modules.

Error Handling: It supports throwing and catching exceptions, which results in cleaner error handling.

Memory Management:

Automatic memory management deallocates the memory instead of manually handling it in the code.

Dynamically Typed:

Datatypes are strongly and dynamically typed; typecasting any variable from one datatype to another causes an exception, so errors are caught at the earliest.

Where is Python Open Source Language Used?

Console Based Application:

Python can be used for developing console-based applications.

Web Applications:

Web applications can be developed using Python. It provides libraries that handle protocols like HTML, XML, JSON, and requests. It provides various frameworks, such as Django, Pyramid, etc., for web application development.

Desktop GUI Application:

Python provides frameworks like Kivy, PyQt, Tkinter PyGUI, etc., for developing desktop GUI applications.

Scientific and Numeric Computing Applications:

Python provides various libraries and packages like SciPy, Pandas, IPython, etc., for developing numeric and scientific computations using Python.

Business Applications:

Python is used for building business applications like ERP, e-commerce applications, etc.

Audio or Video-based Applications:

Python can be used to develop multimedia applications that include images, audio, and videos to create cartoons, etc. Some of the real-time applications are TimPlayer, play, etc.

Machine Learning Applications:

Python contains special libraries for machine learning, namely scipy and numpy, which are great for linear algebra and learning kernel machine learning methods.

Real-time Examples of Python

Various companies are widely using Python as a code base for developing their applications or products. Below mentioned are a few examples.

Google, DropBox, NetFlix, Instagram, Splunk BuzzFeed, FaceBook, Spotify, and many more companies use Python for their development.

The first version of Python was released as Python 1.0 in 1994. Now the latest version is Python 3.10.6, released on August 2023. From Python 1.0 to 3.10, various new features and enhancements to the existing features are being made.

How do you contribute to Python?

Since Python is open source, you can contribute to python by submitting any modules or applications, or you can even raise any bugs or even provide the fixes for them. To contribute, you can submit your work to the official python sites. Some of them are mentioned below.
