.py File — Python Script

Python is a high-level, interpreted programming language known for its emphasis on readability, simplicity, and versatility. Created by Guido van Rossum and first released in 1991, Python uses significant whitespace (indentation) to delimit code blocks, enforcing clean and consistent formatting. PY files contain Python source code that is executed by the Python interpreter (CPython, PyPy, or others). Python has become one of the most popular programming languages worldwide, dominant in data science, machine learning, artificial intelligence, scientific computing, web development (Django, Flask, FastAPI), automation, scripting, and education. The language's extensive standard library ("batteries included") and the massive PyPI ecosystem (over 400,000 packages) provide ready-made solutions for virtually any task. Python supports multiple programming paradigms including procedural, object-oriented, and functional programming. Python 3 (the current major version) introduced significant improvements including better Unicode support, f-strings, type hints, async/await, and walrus operator. Python's simplicity makes it the most popular first programming language in university curricula worldwide.
