Top 13 Key Features of Python That You Must Know

Python is one of the most popular programming languages. It has a lot of advantages, and the demand for the language is growing by the day. 

Python is used in data science, artificial intelligence, machine learning applications, web development, and more. But the most important question is, “Are you using the right features that can make your programming easier or making it hard?” 

This blog helps you to understand which key features of python are important and how you can use them in your programming.

Learn how to use the powerful and key features of Python to be a better programmer.

What is Python?

Python is an interpreted, object-oriented, high-level programming language.  It is powerful because of how easy it is to use! It takes only a few lines of code to make a program that behaves in different ways. 

It is also one of the fastest languages in the world for both learning and writing. However, Python is a great way for beginners to start learning how to code, and seasoned coders will be able to hack away with this as well!

Due to its dynamic nature, it is often used by beginning programmers. It is also used extensively in data science and machine learning because of its readability and flexibility. 

Python can work with a large amount of data, and it is easy to prototype with. Many companies use it. It is a general-purpose language.

Libraries of Python Programming

Here are some libraries of Python programming.

  • Pandas
  • Keras
  • Numpy
  • Eli5
  • TensorFlow
  • Scikit Learn
  • PyTorch

What are the Key Features of Python Programming?

The following are some of the Python features discussed below:

1. Easy To Learn and code  

Python is a high-level programming language that is simple to learn. Its syntax is extremely simple, and the learning curve is extremely smooth.

Anyone can learn to code in Python in a matter of hours or days. It may take some time to master Python and all of its advanced concepts, packages, and modules.

Perhaps as a result of this, many schools, universities, and colleges are teaching Python to their students who are just starting out with the coding.

2. Free and Open-Source

This is one of the best and key features of Python programming. 

Python is developed under an open source license approved by the OSI. As a result, it is free to use, even for commercial uses. 

It is free to download and incorporate into your application. It is also free to modify and redistribute. Python can be acquired from the Python website.

3. Dynamically Typed Language

Python is a dynamically typed programming language. In other words, we aren’t required to declare the data types of the variables we define in Python. 

The Python interpreter’s job is to determine the data types of the variables at runtime based on the types of the expression’s parts. While this property makes coding easier for programmers, it may cause runtime errors. 

4. Large Standard Library

Python has a large standard library that anyone can use. This means that, unlike other programming languages, programmers do not have to write code for everything. 

Libraries are available for image manipulation, expressions, unit testing,  databases, and various other functions. Aside from the standard library, there is a growing collection of thousands of components available in the Python Package Index.

5. High-Level Language

A high-level language (HLL) is a programming language that allows a programmer to write programs that are independent of the type of computer used. 

These languages are considered high-level because they are close to human languages but far from machine languages. 

Python is simpler to learn and understand than middle-level languages like C. We don’t need to remember system architecture or manage memory in Python.

However, high-level language is one of the key features of Python. 

6. Portable

Python is portable in the way that it can run the same code on multiple machines. Assume you’re writing Python code on a Mac. You don’t have to change anything if you want to run it on Linux or Windows later. 

As a result, there is no need to write a program for each platform separately.

7. Interpreted Programming Language

Python is an interpreted language (a programming language that is generally interpreted rather than compiled into machine instructions). 

It is one in which the instructions are read and executed by another program known as the interpreter rather than directly executed by the target machine, and an IDLE (Interactive Development Environment) is packaged alongside Python.

Programming languages like C++ and Java are not interpreted because they must be compiled before they can be run.

8. Expressive

Python only requires a few lines of code to perform complex tasks. To display Hello World, for example, type just one line – print(“Hello World”). Other programming languages, such as Java or C, would require multiple lines to perform this.

9. Large Community Support

Large community support is one of the well-known key features of Python programming.

Python has grown in popularity over the years, with one of the largest communities on StackOverflow and Meetup. If we need help and support with Python, the vast community is always available to help us. 

Many Python questions have already been answered on these sites, and Python users can refer to them as needed.

10. Graphical User Interface (GUI) Support

Another intriguing aspect of Python is that it can be used to create graphical user interfaces (Graphical User Interfaces). We can achieve the same result with Tkinter, PyQt, wxPython, or Pyside. 

Python also has a large number of GUI frameworks and other cross-platform solutions available. Python integrates with platform-specific technologies.

11. Extensible 

If a programming language can be extended to other languages, it is said to be extensible. Python code can also be written in other languages, such as C++, making it a very versatile language.

This means that we can extend our Python code in other languages as well, such as C++.

However, extensible is also one of the key features of python.

12. Object-Oriented and Procedure-Oriented

An object-oriented programming language is one that designs around data and objects rather than functions and logic. 

On the other hand, a programming language is procedure-oriented if it focuses on functions (code that can be reused). One of the most important aspects of Python is that it supports both object-oriented and procedure-oriented programming.

13. Platform Independent

Python’s platform independence is yet another one of the key features of python. In other words, if we write a program in Python, it can run on a variety of platforms, such as Mac, Linux, Windows, and so on. We don’t need to write separate Python code for each platform.

Popularity of Python Compared to Other Programming Languages


We’ve talked about Python and “key features of python” in this blog. I hope you learned something from this. These are the best 13 key features of Python that we have discussed. As previously stated, it is interpreted, dynamically typed, and object-oriented, as well as portable, free, and accessible. That’s a good reason to look into Python. Start learning Python right away to advance your career.

It’s often used for web development and data science. If you’re interested in learning Python, one of the most important things to do is learn what the best practices are.

Frequently Asked Questions

Q. Is Python or C++ better?

Overall, Python outperforms C++ in terms of syntax clarity and simplicity. C++, on the other hand, outperforms in terms of performance, speed, and application breadth. Every programming language is built on C and C++, and Python is built on C specifically for web programming.

Q: What is the importance of learning Python?

Python is now used in a variety of fields, such as Data Science, Natural Language Processing, Machine Learning, Software Engineering, and so on. Python is extremely simple to learn and understand, making it essential in today’s technology-driven world.
