Python Programming Language

What is Python?

Python is a high-level, interpreted programming language created by Guido van Rossum and first released in 1991. Python is known for its simplicity, readability, and versatility, making it an excellent choice for beginners as well as experienced programmers. Python has a wide range of applications, including web development, scientific computing, data analysis, artificial intelligence, and more.

Some features of Python

  • Easy-to-read syntax: Python’s simple and clean syntax makes it easy to learn and understand, reducing the time required to write and debug code.

  • Object-oriented programming: Python supports object-oriented programming (OOP), which enables the creation of reusable and modular code.

  • Large standard library: Python comes with a vast standard library that provides built-in support for many common tasks, such as file I/O, regular expressions, and networking.

  • Cross-platform compatibility: Python is available on various platforms, such as Windows, macOS, Linux, and Unix, allowing developers to write code that runs on different operating systems with minimal modifications.

  • Extensible and embeddable: Python can be extended with modules written in other languages like C, C++, or Java, enabling developers to optimize performance-critical sections of their code. Python can also be embedded into other applications, providing scripting capabilities.

Python “Hello, World!” Example

Once Python is installed, you can write a simple “Hello, World!” program to ensure everything is working correctly. Create a new text file, name it “”, and add the following code:

print("Hello, World!")

Save the file and open a terminal or command prompt. Navigate to the directory where the “” file is located and run the following command:


If everything is set up correctly, you should see the output:

Hello, World!

Python has a vast ecosystem of libraries and frameworks that can be used to simplify various tasks, including:

  1. NumPy: A library for numerical computing and working with arrays and matrices.
  2. pandas: A library for data manipulation and analysis, providing data structures like DataFrame and Series.
  3. matplotlib: A library for creating static, animated, and interactive visualizations in Python.
  4. SciPy: A library for scientific computing, providing functions for optimization, integration, interpolation, and more.
  5. TensorFlow: An open-source machine learning framework developed by Google, used for building neural networks and other machine learning models.
  6. scikit-learn: A library for machine learning and data mining, providing tools for classification, regression, clustering, and more.
  7. Flask: A lightweight web framework for developing web applications using Python.
  8. Django: A high-level web framework for building web applications quickly and with less code.
