Basics of Python: Introduction to Python. Fundamentals of Python. What are the python versions available and who uses them?

Python is among the top five most widely used programming languages, with more than 48% of developers using it worldwide. lications for e-commerce, social media, and other online services. The availability of several frameworks through which such apps can be developed is one factor that has contributed to its popularity among developers. 

Introduction to Python

Python is a simple and efficient language for developers, while also powerful, thanks to its ability to integrate with other languages. Organisations like Google, NASA, Disney, and Industrial Light & Magic have used that capability of Python to achieve success in their projects.

The most common use for Python is websites, including web servers that send out HTML pages and “back end” scripts that gather input or information from databases. 

Other uses of Python include desktop applications, GUI (Graphical User Interface) apps, and games. In most cases, professionals have used C/C++ to create Python-based software.

Fundamentals of Python

Python has a simple syntax and convenient built-in data structures. In addition, it provides powerful features like dynamic typing, functional programming, metaprogramming, and automatic memory management.

Python is known for its readability in code, wide range of technical computing libraries, and the availability of third party plugins through which different capabilities can be added to the language.

The data structures provided by Python include lists, tuples, sets etc. These can be combined to create complex types. It enables users to build their class of data type if needed.

Python is widely used in scientific computing, web development, network programming, the gaming industry, etc.

It has dynamic typing, which means the data types are associated with the objects rather than variables. The speed of Python is another factor that contributes to its widespread use. Since it does not have to compile code before it runs (in most cases), programs run faster than languages like C++ or Java.

Python allows users to add plugins and modules, which means it can easily be extended to include capabilities not available in the basic language. The Python Package Index contains thousands of publicly available libraries for use by programmers.

Python is supported on a wide range of platforms like Windows, Linux, UNIX, Mac OS X, etc., making it more widespread.

Python is readily available. You can download it for free, install and use it, which makes it a part of the top programming languages for many organisations. It has been around since 1989 but continues to grow as its user base increases.

It has some interesting applications that are being built on it. Python-powered gaming applications are a hit with many youngsters. The language is also being used by professionals in the finance and animation industries.

From a business perspective, it offers low entry barriers from all parts of the world and allows organisations to interact globally.

What are the Python versions available, and who uses them?

It is essential to know about the Python version that a programmer uses. The first major release was in 2000, after which it has had several improvements and updates added at regular intervals. 

There are three versions available: 2.7, 3.4, and 3.5, with 2.7 being the most widely used. The versions differ in their syntax, compatibility with modules, and the libraries are included by default.

In July 2010, Python 2.7 was released and is the most popular version after 3.5. Many programmers still use Python 2.7 since it has many third-party libraries available for it. However, there have been no updates to this version after 2015 which means it lacks security enhancements in newer versions of the language.

The latest version is Python 3.5, which was released in September 2015 and contained some beneficial features compared to the previous versions of the software. It includes over 1,500 new modules and many other improvements to make it easier for developers to write more functional applications using Python.

Many programmers still use 2.7 because there are more third-party libraries available. Python 3.5 has a different syntax that makes it challenging to port all existing 2.7 code. Still, the future belongs to the latest version of this programming language.

Who uses Python?

Large organisations like Google, Yahoo, NASA, and the European Space Agency are the biggest users of Python. Companies making use of Python include Instagram, YouTube, BitTorrent, etc. Researchers in the academic sector also extensively use it to create complex scientific applications. Hobbyists (like gamers) love this language for its ease of use and speed.

Python is popular among large corporations since it’s simple to read, easy to learn, and because its libraries and frameworks increase efficiency. It also works well with other languages, making it easy to integrate with existing code when a company wants to upgrade or add on.

Python’s increasing popularity has made it the cornerstone of major organisations like Google, Instagram, Spotify, Quora, and Dropbox.

Many businesses, such as Netflix, Facebook, and Reddit, have even made open-source Python frameworks and libraries available for third-party developers to use.

Python is used in various ways by different businesses, in the backend of prominent social media platforms and recommendation engines, web crawling and indexing, and connecting teams at large organisations.

The Community of Python

The community is represented through a non-profit organisation called the Python Software Foundation (PSF). With a worldwide presence spread over 129 countries, it advocates the development and use of the language. Several registered user groups in various countries, all of whom organise meetings to spread awareness about the language.

The Python Software Foundation also organises Global Python Conference (GPC) as a part of its mission to promote the programming language’s use and standardisation. It is an international gathering where professionals from different backgrounds gather under one roof to discuss Python’s various possibilities and applications.

The community of contributors is another vital factor that has contributed to the success of Python. Many professionals consider it an enjoyable programming language to work with because of its simplicity and stability. The open-source nature enables contributions from individual developers and different organisations and companies.



For individual programmers, Python enables them to build prototypes faster than other languages, which saves both time and money.

Python is a perfect language for beginners and experienced programmers due to its simplicity, ease of use, and vast technical capabilities. It is also one of the languages included in Basic Computer Science courses.

Companies are using Python worldwide to build applications for the web, automation of processes, and scientific research, among others.

This programming language’s most extensive user base is found in educational institutions, followed by several large IT companies.
