Additionally, Python has a large and supportive community that provides extensive documentation and tutorials, making it easier for people to learn and start coding with Python. 

The language is also very versatile and can be used for a wide range of applications, from web development and scientific computing to artificial intelligence and data analysis. These factors contribute to the popularity of Python and make it an excellent choice for people who are just starting out with programming.

2. Easy to Use

This is one of the well-known and important key features of Python. 

Python is a powerful and simple programming language. It’s a good choice for students and new programmers. The syntax is readable and written in English-like coding that anyone can learn.

However, Python was designed to be simple to use, easy to learn, and powerful. It has an extensive library of modules and packages, designed to simplify programming and allow you to complete all sorts of tasks.

3. High-Level Language

Python programming language is a high-level language. It has been used in a number of applications that focus on the internet and the web, as well as on data mining.

Indeed, it was created by Guido van Rossum. Python is high-level because the code is closer to natural languages. It’s a general-purpose programming language because it can be applied to many areas. It is also object-oriented because it is based on objects. 

However, there are a variety of popular programming styles that are used when using Python for coding. The most well-known programming style is object-oriented programming. 

4. Free and Open Source

Python is both free and open-source. This means that you can download and use the language without having to pay any licensing fees, and that the source code for the language is publicly available, allowing anyone to examine and modify it. 

The open-source nature of Python has made it popular among developers and has allowed for a large and supportive community to form around the language. The community contributes to the development of the language by submitting bug fixes, new features, and other improvements. Which are then incorporated into the main codebase and made available to everyone. 

Moreover, the combination of being free and open-source makes Python accessible to a wide range of people and organizations, which has helped to drive its growth and popularity.

5. Dynamic Memory Allocation

Dynamic memory allocation is one of the key features of python. It makes Python a high-level programming language, as it abstracts away many of the low-level details of memory management, making it easier for the programmer to focus on writing code. 

Additionally, dynamic memory allocation can help to prevent memory leaks. This can occur when a program fails to release memory that it is no longer using, causing the program to consume more and more memory over time.

6. Easy to Code

One of Python’s main features is how easy it is to code. Python uses white space indenting to help separate code instead of symbols like curly brackets, semicolons, or keywords like “end” or “for”. Python tries to take the difficulty of parsing out of the coding process. 

However, this is one of Python’s main purposes and why it has become so popular! Python also makes it easy to read your code. The syntax is clear, and at the same time, easy to remember.

7. Easy to Read

One of the key features of Python is its ease of readability. The language is designed with code readability in mind, making it easier for programmers to understand and maintain code written by others. 

Python uses indentation and white space to structure code and signal the start and end of blocks, which eliminates the need for curly braces or other types of brackets that can make code more difficult to read. 

Additionally, Python has a large number of high-level data structures, such as lists and dictionaries, which allow for simple and intuitive manipulation of data. These factors make Python code easy to read, understand, and maintain.

8. Dynamically Typed Language

Yes, Python is a dynamically typed language, which means that the type of a variable is determined at runtime, rather than being specified when the variable is declared. This allows for a high level of flexibility in the way that data can be represented and manipulated in Python. 

In a dynamically typed language like Python, variables do not need to be declared with a specific type, and their type can change during the execution of the program. This allows for greater flexibility in the way that data is stored and processed, as you can use the same variable to store different types of data at different times.

x = 42print(type(x)) # <class ‘int’>x = “Hello, World!”print(type(x)) # <class ‘str’>

9. Automatic Garbage Collection

Python uses automatic garbage collection. This is a feature that automatically manages memory by freeing up memory that is no longer being used by the program. 

In Python, objects that are no longer needed by the program are automatically identified and their memory is automatically released back to the system, making it available for other processes. This is performed by the Python memory manager, which periodically scans the memory heap for objects that are no longer in use, and frees the memory occupied by those objects.

However, this is one of the best key features of python programming. 

10. GUI Programming Support 

Yes, Python has excellent support for GUI (Graphical User Interface) programming. However, there are several popular libraries available that make it easy to create sophisticated graphical user interfaces in Python. 

Some of the most popular GUI libraries for Python include Tkinter, PyQt, wxPython, and PyGTK.

11. Large Standard Library Support

One of the key features of Python is its large and comprehensive standard library. It provides a wide range of functionality that can be used out of the box. 

The standard library is a collection of modules and packages that are included with the Python distribution, and that provide functionality for a wide range of tasks. In addition, it includes file I/O, string manipulation, data persistence, network communication, and much more.

12. Portable language

Python is a portable language, which means that code written in Python can run on multiple platforms with little or no modification. This makes Python a versatile and flexible language that can be used for a wide range of applications, regardless of the underlying operating system.

Furthermore, Python code is executed by the Python interpreter, which is available for a variety of platforms, including Windows, macOS, and Linux. This means that code written in Python can be run on any platform.

13. Interpreted Language

Another of the key features of Python is an interpreted language. It means that code written in Python is executed line by line, rather than being compiled into machine code before being executed. 

However, this has several benefits over compiled languages, such as increased speed of development, as well as greater flexibility in the development process.

14. Object-Oriented Programming Language

Python is an object-oriented programming (OOP) language. Object-oriented programming is a programming paradigm that is based on the concept of “objects”, which can represent real-world entities, such as people, cars, or animals.

In OOP, objects are created by defining classes, which serve as templates for creating objects. Classes define the attributes and methods that objects of that class will have. Attributes are variables that store data, while methods are functions that perform actions.

15. Database Support

Python has excellent support for working with databases. Python provides a wide range of libraries for working with different types of databases, including relational databases (such as MySQL and PostgreSQL), NoSQL databases (such as MongoDB and Cassandra), and many others.

One of the most commonly used libraries for working with databases in Python is SQLite. SQLite is a lightweight, file-based database that is easy to use and ideal for small to medium-sized applications.


Python has been around for a long time and has had a lot of development and improvements over the years. It’s a very versatile programming language that is used across many different industries. It’s a powerful language, especially in the data science space. In the next five years, Python is going to be one of the most important programming languages out there, especially as data analytics and big data become more important.
