What are the key features of Python?

  • Python is an interpreted language. That means that, unlike languages like C and its variants, Python does not need to be compiled before it is run. Other interpreted languages include PHPand Ruby.
  • Python is dynamically typed, this means that you don’t need to state the types of variables when you declare them or anything like that. You can do things like x=111 and then x="I'm a string" without error
  • Python is well suited to object orientated programming in that it allows the definition of classes along with composition and inheritance. Python does not have access specifiers (like C++’s publicprivate), the justification for this point is given as “we are all adults here”
  • In Python, functions are first-class objects. This means that they can be assigned to variables, returned from other functions and passed into functions. Classes are also first class objects
  • Writing Python code is quick but running it is often slower than compiled languages. Fortunately,Python allows the inclusion of C based extensions so bottlenecks can be optimized away and often are. The numpy package is a good example of this, it’s really quite quick because a lot of the number crunching it does isn’t actually done by Python
  • Python finds use in many spheres – web applications, automation, scientific modelling, big data applications and many more. It’s also often used as “glue” code to get other languages and components to play nice.

    Some programming-language features of Pythonare: A variety of basic data types are available: numbers (floating point, complex, and unlimited-length long integers), strings (both ASCII and Unicode), lists, and dictionaries. Python supports object-oriented programming with classes and multiple inheritance

    1. Features of Python Programming Language

    At some point in time, we had about as many programming languages as we could count on our fingers. Today, there are so many, and all with their own specialities. But what makes a language unique is its features. And ultimately, it is its features that get it chosen or passed for a project. So before beginning with deeper concepts of Python, let’s take a look at the major features of python programming language that give you reasons why you should learn Python as compared to R or other tool. So lets start with the Features of Python Programming Language.

    Easy

    When we say the word ‘easy’, we mean it in different contexts.

    Easy to code

    As we have seen in earlier lessons, Python is very easy to code. Compared to other popular languages like Java and C++, it is easier to code in Python. Anyone can learn python syntax in just a few hours. Though sure, mastering Python requires learning about all its advanced concepts and packages and modules. That takes time. Thus, it is programmer-friendly.

     Easy to read

    Being a high-level language, Python code is quite like English. Looking at it, you can tell what the code is supposed to do. Also, since it is dynamically-typed, it mandates indentation. This aids readability.

    Expressive

    First, let’s learn about expressiveness. Suppose we have two languages A and B, and all programs that can be made in A can be made in B using local transformations. However, there are some programs that can be made in B, but not in A, using local transformations. Then, B is said to be more expressive than A. Python provides us with a myriad of constructs that help us focus on the solution rather than on the syntax. This is one of the outstanding python features that tells you why you should learn Python.

    Free and Open-Source

    Firstly, Python is freely available. You can download it from the following link
    https://www.python.org/downloads/
    For insight on how to download and install Python, refer to our tutorial on Python Installation.
    Secondly, it is open-source. This means that its source code is available to the public. You can download it, change it, use it, and distribute it. This is called FLOSS(Free/Libre and Open Source Software). As the Python community, we’re all headed toward one goal- an ever-bettering Python

    High- Level

    As we discussed in point 2b, it is a high-level language. This means that as programmers, we don’t need to remember the system architecture. Nor do we need to manage the memory. This makes it more programmer-friendly and is 1 of the key python features.Any doubt yet in the features of Python. Please ask.

    Portable

    Let’s assume you’ve written a Python code for your Windows machine. Now, if you want to run it on a Mac, you don’t need to make changes to it for the same. In other words, you can take one code and run it on any machine, there is no need to write different code for different machines. This makes Python a portable language. However, you must avoid any system-dependent features in this case.

    Interpreted

    If you’re any familiar with languages like C++ or Java, you must first compile it, and then run it. But in Python, there is no need to compile it. Internally, its source code is converted into an immediate form called bytecode. So, all you need to do is to run your Python code without worrying about linking to libraries, and a few other things.
    By interpreted, we mean the source code is executed line by line, and not all at once. Because of this, it is easier to debug your code. Also, interpreting makes it just slightly slower than Java, but that does not matter compared to the benefits it has to offer.
