Python provides many useful features which make it popular and valuable from the other programming languages. It supports object-oriented programming, procedural programming approaches and provides dynamic memory allocation. We have listed below a few essential features.
In Python, we don’t need to declare the type of variable because it is a dynamically typed language.
For example, x = 10
Here, x can be anything such as String, int, etc.
Features of Python
Easy to learn and simple to code:
- Python has a smooth learning curve. It is easy to learn.
- Python has a simple syntax and Python code is easy to understand.
- Since it’s easy to understand, you can easily read and understand someone else’s code.
- Python is also easy to write because of its simple syntax.
The Python language is designed to make developers life easy. Reading a Python code is like reading an English sentence. This is one of the key reason that makes Python best for beginners. Python uses indentation instead of curly braces, unlike other programming languages. This makes the code look clean and easier to understand.
First, let’s learn what is 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 tell you why you should learn Python.
Firstly, Python is freely available. You can download it from the python official website: https://www.python.org/downloads/
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.
Python is an interpreted language. It comes with the IDLE (Interactive Development Environment). This is an interpreter and follows the REPL structure (Read-Evaluate-Print-Loop). It executes and displays the output of one line at a time. So it displays errors while you’re running a line and displays the entire stack trace for the error. there is no need to compile python code this makes it easier to debug our code. The source code of python is converted into an immediate form called bytecode.
Python is not statically-typed like Java. You don’t need to declare data type while defining a variable. The interpreter determines this at runtime based on the types of the parts of the expression. This is easy for programmers but can create runtime errors.In Python, When we assign some value to the variable, it automatically allocates the memory to the variable at run time. Suppose we are assigned integer value 15 to x, then we don't need to write int x = 15. Just write x = 15.
Extensible and Embeddable
Python is extensible. You can use code from other languages like C++ in your Python code. It is also embeddable. You can embed your Python code in other languages like C++.
Python can run equally on different platforms such as Windows, Linux, UNIX, and Macintosh, etc. Python is platform-independent. If you write a program, it will run on different platforms like Windows, Mac and Linux. You don’t need to write them separately for each platform. 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. This makes Python a portable language. So, we can say that Python is a portable language. It enables programmers to develop the software for several competing platforms by writing a program only once.
Python is a high-level language. When we write programs in python, we do not need to remember the system architecture, nor do we need to manage the memory.Also, we need not manage memory. This makes it more programmer-friendly and is one of the key python features.
You can use Python to create GUI (Graphical User Interfaces). You can use tkinter, PyQt, wxPython or Pyside for this.
A programming language that can model the real world is said to be object-oriented. It focuses on objects and combines data and functions.
Contrarily, a procedure-oriented language revolves around functions, which are code that can be reused.
Python supports both procedure-oriented and object-oriented programming which is one of the key python features.
It also supports multiple inheritance, unlike Java.
A class is a blueprint for such an object. It is an abstract data type and holds no values.
Large Standard Library
Python has a large standard library which provides a rich set of module and functions so you do not have to write your own code for every single thing. There are many libraries present in python for such as regular expressions, unit-testing, web browsers, etc.The standard library is large and has many packages and modules with common and important functionality. If you need something that is available in this standard library, you don’t need to write it from scratch. Because of this, you can focus on more important things. You can also install packages from the PyPI (Python Package Index) if you want even more functionality.
Python is also scalable. These were some important features of Python. I hope that our article was fruitful to you and has helped you to choose your path.
