Introduction

          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 is an easy-to-learn language that allows developers to focus on problem-solving, rather than syntax.

Key Features of Python

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

1. Easy to Learn 

          Python is a high-level programming language that is simple to learn. Anyone can learn to code in python within a few days of learning.   It will take some time to master Python and all of its concepts, packages, and modules. However, when compared to other popular languages such as C, C++, and Java, learning the basic Python syntax is quite simple. 

2. 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):

	print(n)

3. 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.

4. 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.

5. Dynamically Typed Language

          One of the main features of Python is that it is a dynamically typed language. This means that when coding, developers do not need to declare the data type of a variable they define. Instead, the Python interpreter determines the data type at runtime from the parts of the expression. This allows for easier coding but also has the potential for run-time errors since Python follows "duck typing" - an object's identity is based on its behavior rather than its class definition.

6. Free and Open Source

          Python is an open-source programming language and it uses a BSD (Berkeley Software Distribution) license, which means that the language can be used for any purpose without requiring royalty payments or restrictions on its use. This allows developers to make modifications to the code without tearing apart original programs or offending copyright laws. Additionally, this licensing system allows newbies to enter the development scene as there are no legal issues associated with using open-source software. Python is freely available to download, install and use from python.org

7. Object-Oriented Programming Language

          One of the essential features of Python is its support for object-oriented programming. This means that instead of having data and instructions stored in separate places inside a program, everything involved in a certain task can be grouped together into “objects”. This model makes it easier to use and understand code, as well as better scalability when developing programs and applications. Python supports inheritance, encapsulation, and polymorphism.

8. GUI Programming Support

          One of the top feature of python is its support for Graphical User Interface (GUI). Python features a Graphical User Interface to develop desktop applications. This makes it easier for the users to code in a python programming language. There are many modules available in python like PyQT5, Tkinter, Kivy, etc. to develop applications. In addition, Python offers a wide range of GUI frameworks and other cross-platform solutions.

9. High-Level Language

          Python is a high-level programming 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 makes it a user-friendly language and adds an important feature of python.

10. Extendable and Embeddable Syntax

          Python’s extendable and embeddable syntax is one of its best features, allowing developers to easily create new operations without having to rewrite code that already exists. This allows for much more flexibility when developing applications as developers can call on existing libraries to quickly and easily add new functionality in various scenarios. This reduces the need to manually write code, making development much faster and easier.

11. Portable and Extensible

         Python is one of the most portable programming languages available in the market. It’s cross-platform and can run on any operating system such as Windows, Mac, or Linux. This makes it an excellent choice for developers who want to build cross-platform applications. Additionally, Python’s extensibility allows new functionality to be easily added without having to rewrite existing code from scratch, adding another layer of complexity and flexibility to the language. 

12. 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. Additionally, being an interpreted language also enables Python to determine the type of data at run time, which helps reduce errors when developing programs. 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.

13. Large Standard Library Support

          Python features 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.

14. Dynamic Memory Allocation

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

15. Interactive Mode

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

16. Database Support 

          Python features 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 the database, python uses the following libraries:
  • psycopg2 for PostgreSQL.
  • MySQLdb for MySQL. 
  • cx_Oracle for Oracle Database.

17. Automatic Garbage Collection

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

18. Integrated

          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.
