Python Features — Python Tutorial

Python provides many useful features that make it popular and valuable compared to other programming languages. It supports object-oriented programming and procedural programming approaches and provides dynamic memory allocation. We have listed below a few essential features.

1) Easy to Learn and Use

Python is easy to learn as compared to other programming languages. Its syntax is straightforward and much the same as that of the English language. There is no use of the semicolon or curly bracket; the indentation defines the code block. It is the recommended programming language for beginners.

2) Expressive Language

Python can perform complex tasks using a few lines of code. A simple example, the hello world program you simply type print(“Hello World”). It will take only one line to execute, while Java or C takes multiple lines.

3) Interpreted Language

Python is an interpreted language, which means the Python program is executed one line at a time. The advantage of being an interpreted language is that it makes debugging easy and portable.

4) Cross-platform Language

Python can run equally well on different platforms such as Windows, Linux, UNIX, Macintosh, etc. 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.

5) Free and Open Source

Python is freely available for everyone. It is freely available on its official website, www.python.org. It has a large community across the world that is dedicatedly working towards make new python modules and functions. Anyone can contribute to the Python community. The term "open-source" means “anyone can download its source code without paying a penny.”

6) Object-Oriented Language

Python supports an object-oriented language, and concepts of classes and objects come into existence. It supports inheritance, polymorphism, and encapsulation, etc. The object-oriented procedure helps programmers write reusable code and develop applications with less code.

7) Extensible

It implies that other languages such as C/C++ can be used to compile the code, and thus it can be used further in our Python code. It converts the program into byte code, and any platform can use that byte code.

8) Large Standard Library

It provides a vast range of libraries for the various fields such as machine learning, web developer, and also for the scripting. There are various machine learning libraries, such as TensorFlow, Pandas, Numpy, Keras, PyTorch, etc. Django, Flask, and Pyramids are the popular frameworks for Python web development.

9) GUI Programming Support

A graphic user interface is used for the developing desktop application. PyQT5, Tkinter, and Kivy are the libraries that are used for developing the web application.

10) Integrated

It can be easily integrated with languages like C, C++, and JAVA, etc. Python runs code line by line like C, C++, and Java. It makes it easy to debug the code.

11. Embeddable

The code of the other programming language can be used in the Python source code. We can use Python source code in another programming language as well. It can embed other languages into our code.

12. Dynamic Memory Allocation

In Python, we don’t need to specify the data type of the variable. When we assign some value to the variable, it automatically allocates the memory to the variable at run time. Suppose we are assigned the integer value 15 to x, then we don’t need to write int x = 15. Just write "x = 15."
