What is python used for?
Python is true general purpose language . It can be used for pretty much anything. It's one of the most versatile languages in the world. With the vast amount of libraries available for it, it makes development much simpler. In particular, Python is excellent for web development, numerical and scientific computing, Internet of Things, robotics , natural language processing, etc.
Easy to Understand
Python is much easier as compared to other programming languages . It is an easy-to learn language and provides a stepping stone into the world of programming. Python handles a lot of complexity for you, so it is a very beginner-friendly in that it allows beginners to focus on learning programming concepts and not have to worry about too much details. Python basics is helpful in creating a solid base for the student's programming career ahead of C and C++. However, if you are just beginning your path towards a programming career , you might want to start by learning Python, as it is less complex.
One of the main reasons is the simplicity of its code which makes it easily comprehensible for beginners. Being a very high level language, codes in Python are written in plain English without any complicated syntax. You don't have to worry about curly brackets or white spaces. Also, Python has a set of rules, known as PEP 8 , that tell every Python developer how to format their code. This means you always know where to put new lines and, more importantly, that pretty much every other Python script you pick up, whether it was written by a novice or a seasoned professional, will look very similar and be just as easy to read. Serving to be a backbone of Google , this coding language uses fewer lines of code unlike Java and C++.
As a dynamically typed language , Python is really flexible. Dynamic typing means that runtime objects (values) have a type, as opposed to static typing where variables have a type. Python Variables have no type. Only the object that a variable references has a type. Variables are simply names pointing to objects. var = 5 makes the variable name var to refer to the integer 5. Later, var = "hello" makes the variable name var to refer to a string containing "hello". Static typed languages would have you declare int var and then var = 5, but assigning var = "hello" would have been a compile time error. This means there are no hard rules on how to build features, and you'll have more flexibility solving problems using different methods.
Python is not specialised to a specific target of users (like R for statistics, or PHP for web programming). It has many in-built functions which would help you develop things faster. Using Python would help you simulate things faster, if you are looking for it. Even you can create you own functions which would help you understand the concepts of Computer Science thoroughly.
Python's standard library is very extensive and huge. Almost all of it is collected on https://pypi.python.org , pronounced "pie-pee-eye" or, more commonly called "the CheeseShop" . The library contains built-in modules (written in C) that provide access to system functionality such as file I/O that would otherwise be inaccessible to Python programmers , as well as modules written in Python that provide standardized solutions for many problems that occur in everyday programming. There are libraries for pretty much any use case you can come up with, from image manipulation , to scientific calculations, to server automation.
The Python programming language has a global community with millions of software developers who interact online and offline in thousands of virtual and physical locations. Most, if not all of them, are members of the Python Software Foundation (PSF). The PSF is a 501(c)(3) non-profit with the mission to "promote, protect, and advance the Python programming language, and to support and facilitate the growth of a diverse and international community of Python programmers." Python has user groups everywhere, usually called PUGs, and does major conferences on every continent other than Antarctica. The larger a community, the more likely you'd get help and the more people will be building useful tools to ease the process of development.
