Here is full information about Python, one of the most popular programming languages in the world:
📌 Overview
- Name: Python
- Type: High-level, interpreted, general-purpose programming language
- Created By: Guido van Rossum
- Initial Release: 1991
- Current Major Version: Python 3.x (Python 2 is deprecated)
- License: Python Software Foundation License (open source)
- Official Website: https://www.python.org
🧠 What is Python?
Python is a high-level programming language known for its readable syntax and versatility. It supports multiple programming paradigms including:
- Procedural programming
- Object-oriented programming
- Functional programming
Python is widely used in various domains such as web development, data science, artificial intelligence, automation, scientific computing, and more.
🎯 Key Features
1. Easy to Learn and Use
- Simple and clean syntax that resembles natural language.
- Ideal for beginners and experienced developers alike.
2. Interpreted Language
- Python code is executed line by line by an interpreter.
- No need for compilation before running.
3. Dynamically Typed
- No need to declare variable types explicitly.
- Types are determined at runtime.
4. Large Standard Library
- Includes modules for file I/O, system calls, web protocols, databases, text processing, and more.
- Often called “batteries included”.
5. Cross-Platform
- Runs on Windows, macOS, Linux, and many other systems.
6. Extensive Third-Party Ecosystem
- Thousands of packages available via PyPI (Python Package Index).
7. Supports Multiple Paradigms
- Object-oriented, procedural, and functional programming.
🧱 Python Syntax Example
# Hello World example
print("Hello, World!")
# Function definition
def greet(name):
return f"Hello, {name}!"
print(greet("Alice"))
