I: Introduction

A: From the earlier times, there have been many programming languages. Each one is designed to solve a particular problem and is heavily used in a particular field. To give a brief idea about each of them, I am going to design this article.

II: Body

A: First of all, I want to introduce you to Python language. It is a general purpose high-level programming language created by Guido van Rossum in 1989. In simple words, you can say that it is a programming language for scripting purposes. It is available free of cost and free from any license. Being a general purpose programming language, it can be applied to every field you think of. It has been used in scientific, industrial and commercial fields extensively. It is a powerful programming language with a library of more than 3000 modules and a large number of third party libraries too.

Python has been used for web development, desktop applications, GUI's, databases, network programming etc. Apart from being used as a standalone language, it is also widely used as an extension language for other programs like Adobe Photoshop, AutoCAD etc. You can even use python to control robots or build your own android apps!

The syntax of python is extremely readable and simple, which makes it ideal for beginners. It is easy to learn and use with its simple and clean syntaxes. Its clean and whitespace less codes make it an easy read and understand and hence very popular in beginners and kids (because they can read the code easily :) ).

Another most important feature of python is that it is object oriented. This means that different pieces of code can interact with each other through objects and message passing. And these messages can be sent through various channels such as mail, message boxes etc. The features of OOP makes programmers' job really easy when it comes to extending the software in future. Python supports both Procedural and Object Oriented styles of programming.

Python has been built on top of C and C++ and therefore is compatible with existing C and C++ programs and libraries and hence very useful in developing complex systems in shorter time than other languages. Also, it shows some remarkable performance improvement over traditional languages like C/C++ especially in tasks like data manipulation, text processing and matrix multiplication.

Python has got another great feature -- it is open source! As mentioned above, it is available free of cost without any license fees! There are no restrictions whatsoever! This makes it an ideal choice for professional developers who are working on projects where the source code should be kept confidential. The source code of python itself is freely available to all users. You can download the script from its official site.

There are many online courses available on the internet to learn the basics of python programming for beginners. These lessons are not only easy to follow but are also interesting for the students. They are so interesting that you will never feel bored while learning python. Once you have gone through these lessons, you will definitely want to learn more about this versatile language. You can also learn python through books or video tutorials. The best thing about learning python through video tutorials is that you can go through them at your own pace without worrying about missing out on certain points because you are already late for your next class! These online tutorials are also available for free unlike other paid tutorials. You can simply download them from various websites or watch them on youtube to learn python fast!

III: Conclusions

I hope this article has given enough information about what you need to know about python language to start using it for your daily life programming needs. With its fast growing popularity, there are many good reasons why you should learn python today!
