          Python is the most popular language that offers a wide variety of career options. It is a free and open-source language used in web applications, data science, artificial intelligence, machine learning, and so many other programs. Python easy to learn language allows developers to focus on problem-solving, rather than syntax.

Key Features of Python

Python is a popular language because of its features. Following are the key features of Python.

Python Easy to Learn 

          Learning a  Python  programming  language  is  easy  because  of the simple structure and simple syntax of the language. It is like writing an English language using space. Because of this python easy to learn language

Easy to Use

          Python does not need curly brackets ‘{‘ or semicolon ‘;’ instead it uses indentation for differentiating code blocks and which automatically beautify the code structure. It allows users to think like a programmer and not to focus on syntax.
E.g. For loop
 For n in range(10):


Easy to Read

          Because of its simple structure and indentation, it is easy to read. In other programming language does not use indentation like java, c, c++.
e.g. In java, print the “Hello World” program as follows.
public class demo{
public static void main(String []args){
System.out.println("Hello World");
In python print the “Hello World” program as follows. 
class Person:
    def display:
      print(“Hello World”)
Above program shows that because of indentation python program is easy to read and understand.

Easy to Code

          As compared to other programming languages like Java, C++, C#, Python is easy to code. Python basic syntax can be learned in a few hours of study.

Dynamically Typed Language

          This is one of the key features of python. Python is a dynamically typed language, i.e. there is no need to declare a type of variable. It is decided at run time. Type checking is done at run time 

Free and Open Source

          This is one of the key features of python. Python is freely available to download, install and use from There is no need to pay any type of charge for this. Libraries of python are open source. Anyone could use modules and functions of python.

Object-Oriented Programming Language

          Python is an object-oriented programming language. Everything in a python is an object. Python supports inheritance, encapsulation and polymorphism.

GUI Programming Support

          Python uses a Graphical User Interface to develop desktop applications. There are many modules available in python like PyQT5, Tkinter, Kivy etc. to develop applications.

High-Level Language

          Python is a high-level  language. It  uses a  common  English  language  for  coding  that is more understandable to the user. Because of this python execution is a little bit slower than low-level languages. It is a user-friendly language.

Extension feature

          This is one of the key features of python. We can use other language code extensions in the python script. For C and C++ language use CPython, for Java use Jython, Py4J.

Python is a Portable language 

          This is one of the key  features  of  python. Python  programs  run on  various  platforms without changing the code. The same code can be run on Windows, Linux or Mac machines. So it is called cross-platform language. 

Python is an Interpreted Language

          Python is an Interpreted Language. Its code is executed line by line. Because of this, there is no need to worry about linking to libraries, syntax and type checking which makes it easy to debug the code. Python program source code is converted into an immediate form called byte code (.pyc). This byte code is executed by a python interpreter. It converts it into machine-executable code

Large Standard Library Support

          Python  supports a large number of  libraries  for  regular expression,  web browsers,  databases, image processing, unit testing etc. There is no need to write code for everything, just import the module and use their methods.

Dynamic Memory Allocation

          Python automatically assigns memory to the variable. There is no need to declare data type.
X = 50
It assigns a value of 50 to the variable X.

Interactive Mode

          Python programs can write and test using a prompt that directly interacts with an interpreter.

Database Support 

          Python provides an easy interface to Database systems like MySQL, MongoDB, SQLite etc.
SQLite is a built-in database in python stored in a single file. To connect database, python use the following libraries:
  • psycopg2 for PostgreSQL.
  • MySQLdb for MySQL. 
  • cx_Oracle for Oracle Database.

Automatic Garbage Collection

          This is one of the key features of python. Python supports automatic garbage collection. Memory block that is no longer used free by the garbage collector. It deletes unwanted objects to free space.


          Python can be easily integrated with other existing programming languages ​​such as C, C ++, Java, etc. This allows everyone to use it to improve the performance of existing systems and make them more robust.


          In this blog, we learned what are the key features of python. Python is an interpreter, dynamically-typed, and object-oriented programming language. It is also free, easy to learn, easy to use and a portable language.
