Wtf does this do

This repository was a collection of short, practical Python code snippets covering common programming tasks. Each snippet was designed to be small enough to read and understand quickly, with an explanation and examples alongside the code. As of May 2023, this repository and others in the 30-seconds family were merged into a single unified repository called 30-seconds-of-code. New activity, contributions, and updates happen there rather than here. The snippet content itself is still accessible on the project website at 30secondsofcode.org, where you can browse the Python collection, search by name or topic, and copy code directly from the page. The snippets are licensed under CC-BY-4.0, meaning they can be reused freely with attribution. This is a learning and reference resource aimed at developers who want quick examples for everyday Python tasks, not a library you install or a framework you build on.
