What is Python?

Python is a powerful, versatile, and beginner-friendly high level programming language.

  • Readability: With clear and simple syntax python resembles plain English. Therefore, Python code is easier to learn, understand and write compared to some other programming languages.
  • Large Standard Library: Python comes with a very huge collection of built-in modules, functions, and libraries as a toolkit for many tasks without needing to write everything from scratch.
  • Versatility: Python is used in a wide range of applications, such as web development, data analysis, machine learning, scripting, and scientific computing, etc.
  • Strong Community: Python has a large and active community of developers, providing extensive support, libraries, and learning resources.
