What is Python? Python is a general-purpose programming language, which is easy to learn and dynamically initialised. It has an easy and elegant syntax, with high-level and dynamic semantics, which makes it an ideal language for beginners, scripting and rapid application development. Python was first released in 1991 and created by Guido van Rossum, a Dutch programmer best known as the author of the Python programming language, who wanted to designed a language very simple to write and easy to read. Thus, Python is much easier to learn than any other programming languages. And it helps you create beautiful applications, with less effort. But you're wondering: What features and benefits does Python offer? There are many features provided, so are the benefits of learning Python, especially as your first language... Let's start with the benefits of learning Python. Easy: Python is the best languages to get started with and the language preferred by beginners and pros alike. Its easy syntax and high-level features makes it one of the best languages, for anybody who wants to start programming. Free: Python is an open source language, which means that it is free for everyone to use. It can be freely modified and redistributed for any purpose, commercial or not. Application: Python can be used to develop almost anything, desktop mobile and web applications. Plus it is very useful in many areas: data analysis, artificial intelligence, machine learning and so forth. Library support: Python has a massive support base, thanks to the fact that it is open source and community developed. Millions of like-minded developers work with the language on a daily basis. And they continue to improve core functionality, which makes Python even better and more efficient. Thus, it is a great way to network with other developers, share and develop your skills. You can now understand why people in the world love Python so much. But, What are its features? Simplicity: Python is a language that is remarkably easy to learn, which means that it is much easier to get your programs up and running. Since it requires a simple elegant and beginner friendly syntax, that focuses on readability, the programs you write are much easier to read - even if you are not a skilled programmer. This is mainly because it is closer to the human language, or how we write words, instead of a language that computers used to read. Developers can read and translate Python code much easier than any other languages. In turn, this reduces the cost of program maintenance and development, because it allows teams to work collaboratively and without significant language or experience barriers. Interpreted: Python supports multiple programming paradigms, including procedural, object-oriented and functional programming. Most importantly: Python is an interpreted language, which means that the written code is actually not translated into a computer readable format... Python codes are executed line by line, which makes debugging errors much easier and efficient. But this comes at a cost, as it is much slower than other compiled programming languages. Object orientation: object-oriented programming is an approach used for modeling concrete and real world entities into software objects, which have some data associated with them and can perform certain functions. For instance, an object could represent a person with a name, an age, an address, etc. And with behaviors like: walking, talking or running. Its object oriented approach aims to help programmers write clear and logical code, for small and large-scale projects. Portability: there is no exclusivity, as Python and all the necessary tools are available on all major platforms. It is compatible with a long list of computers and operating systems, like Windows, Linux, Mac OS and more. Furthermore, it uses a similar interface on each one of those platforms, which means you can jump between them easily - and if necessary. Embeddable and extensible: Python can be embedded into an application, which will provide a programmable interface for the users of this app. This is a great feature, if you are putting together an app that will require working with Python in a terminal. Additionally, Python supports the use of modules and packages, which means that programs can be designed in a modular style, and code can be reused across a variety of projects. Even better, it can be shared and scaled for use in other projects, once you have developed the module or package that you need. It is very easy to import or export libraries. Python comes with the Standard Python Library, offering integrated support for a variety of common programming tasks, like syncing with web servers, searching through text and modifying files... For a majority of other languages, you have to create this content from scratch. Python also has an amazing community that has built a number of additional useful tools. And you could use them in your own programs. Do you need to work with PDF documents? There is a comprehensive tool for that! Want to collect data from web pages? No need to start from scratch: Python powers Django, a complete and open source web application framework, which can be used to simplify and speed the development process. Open source: Python has a massive support base, thanks to the fact that it is open source and community developed. Millions of like-minded developers work with the language on a daily basis, and they continue to improve core functionality. The latest version of Python continues to receive enhancements and updates. Therefore, it is a great way to network with other developers, share and develop your skills. One of the most promising benefits of python is that the Python interpreter and the extensive standard library are freely available, in both source and binary forms, and for all the major platforms. It can be downloaded from the Python web site and may be freely modified or redistributed for any purpose, commercial or not. Since Python is available under an open-source license there are no licensing fees either, despite the fact that it is copyrighted. The same site also contains distributions and pointers to many free third-party Python modules, as well as programs and tools. But also additional documentation and so on. If this description of Python over your head don't worry, you will understand it soon enough. What you really need to take away from these sections is that Python is a programming language used to develop softwares and web apps, including mobile. It is relatively easy to learn, since the necessary tools and documentations are available to all and free of charge. That makes python accessible to almost anyone... If you have the time to learn, you can create some amazing things. Therefore it can be used as a stepping stone into other programming languages and frameworks. Anyone can begin working with the language, all it takes is a bit of patience and a lot of practice. If you are an absolute beginner and this is your first time working with any type of coding language, Python is definitely something you want. But, Why is Python getting so popular? Because of all its features and benefits, you might have heard that Python is popular. On one hand, it may seem that it doesn't really matter how popular language is, if you can build the app you want to build with it. But for better or worse, in software's development: popularity is a strong indicator of the high quality of libraries you will have available, as well as the number of job openings. So, is Python actually that popular? YES, and there are plenty of stats to back this one. Let's look at some analytics available and pre sented by stackoverflow.com. They run as its called: stack overflow trends. Here you can look at the trends for various technologies by tag. When you compare Python to the other likely candidates that you could pick to learn programming, you will see one is unlike the others.
