What is Python ?
Python is a high-level programming language known for its readability and versatility. Python, created by Guido van Rossum, is a general-purpose programming language that was first released in 1991. It supports various programming paradigms, including procedural, object-oriented, and functional styles. Python’s clean syntax and indentation-based structure make code easy to read and write.
It features a dynamic type system, meaning variable types are inferred at runtime. Python’s rich standard library, cross-platform compatibility, and extensive third-party packages empower developers to build applications for web development, data analysis, artificial intelligence, automation, and more. Its interpreted nature allows rapid development and testing.
Overall, Python is a beginner-friendly, powerful language with a strong community and diverse applications.
Features of Python:
Readability: Python’s clean syntax and indentation-based structure enhance code readability, making it more human-friendly.
Dynamically Typed: Variables are not explicitly declared; their type is inferred at runtime, allowing flexible programming.
Cross-Platform: Python code runs on different platforms without modifications, promoting portability.
Multi-Paradigm: It supports procedural, object-oriented, and functional programming paradigms.
Rich Standard Library: Python offers a comprehensive library that facilitates various tasks, from file handling to web development.
Interpreted: Python code is executed line-by-line by an interpreter, allowing quick development and testing.
High-Level Data Structures: Built-in data structures like lists, dictionaries, and sets simplify complex operations.
