Why Python?

There are so many “Why” questions around Python programming language. Such as:

Why should I start coding with Python?
Why is Python programming language so popular?
Why has Python programming language been so successful as a programming language?
Why do professional coders prefer Python for development?

Everyone has different reasons, different needs and situations to start coding with Python. So, we have compiled 5 top reasons for Why Python is The King right now?

1. Python’s core design philosophy

Python’s core design philosophy emphasizes:

Beautiful is better than ugly.
Explicit is better than implicit.
Simple is better than complex.
Complex is better than complicated.
Readability counts.

This design philosophy caries a very fine balance between code readability and the learning curve. It empowered students to learn better, faster and easier. And empowered professionals to increase productivity, since there is no compilation step, the edit-test-debug cycle is incredibly fast. Debugging Python programs is easy: a bug or bad input will never cause a segmentation fault. This accelerated the growth of python in the academia and the industry, a lot of python development community and forums created on the Internet. A huge coding repository to help the coders along with constant upgradations to the language. The object-oriented nature helped in creating very innovative and powerful libraries for very diverse applications.

Benefits:

It is a language that is remarkably easy to learn.
The code is easy to read and understand.
Several big companies use Python.
Very active development forums and communities online.
Python has a syntax that allows developers to write programs with fewer lines than some other programming languages.
Python runs on an interpreter system, meaning that code can be executed as soon as it is written. This means that prototyping can be very quick.
Python can be treated in a procedural way, an object-orientated way or a functional way.
Python uses new lines to complete a command, as opposed to other programming languages which often use semicolons or parentheses.
Python relies on indentation, using whitespace, to define scope; such as the scope of loops, functions and classes. Other programming languages often use curly-brackets for this purpose.

2. Python is Open Source

Python programming language is developed under an OSI-approved open source license.
Python is compatible with Windows, Linux, macOS, many brands of Unix, OS/2, and more.
It uses a similar interface on each platform, so you can jump between them easily.
A community of millions of like-minded developers work with the language regularly.

Benefits:

It free to use and distribute, including for commercial purposes.
There are IDE (Integrated Development Environment) available on all platforms which are fairly similar as well.
Under an active community, it provides you with a great way to network with other developers.
The PyPI repository – Thanks to the large community of Python programmers, over 134,740 projects in the Python Package Index (PyPI) exist to serve all kinds of needs.
Its development is driven by community collaborates for its code through webinars, conferences, mailing lists, social media groups and provides for its numerous modules.

3. Python is Trending

Python has been the fast-growing language among the top 5 languages. Partially due to boom in AI, Machine Learning and Big Data. Since Python is easy to understand, requires lesser lines of codes to do a specific task and it already being open source, Major technological players have betted on Python for the product development. This helped in making python the #1 programming language in 2018, according to the IEEE Spectrum ranking, and it is the #1 “Most Wanted” and #2 “Most Loved” language, according to StackOverflow’s 2019 Developer Survey.

Dedicated community groups and forums to find advice, mentorship, inspiration or just to chat about How awesome is Python?
Active community drives demand for Python in Industry.

How is python used?

Python is a general-purpose programming language, which is another way to say that it can be used for nearly everything. Most importantly, it is an interpreted language, which means that the written code is not translated to a computer-readable format at runtime.

The concept of a “scripting language” has changed considerably since its inception, because Python programming language is now used to write large, commercial-style applications, instead of just banal ones. This reliance on Python has grown even more so as the internet gained popularity.

Python has several applications in Technical domain, they include:

Image and Text Processing
Graphic Design Applications
Scientific and Computational Applications
Games
Web Frameworks
Web Scraping
Data Analytics
Enterprise and Business Applications
Operating Systems
