## What it is
PyFormat.info is a single-page cheat sheet documenting Python's old-style (%) and new-style (.format()) string formatting with practical, side-by-side examples. The site is statically generated from executable test cases, ensuring all examples are verified to produce the shown output.

## Use cases
- learn python string formatting with examples
- look up how to pad or align strings in python
- compare old-style % formatting with str.format
- find examples of formatting numbers and dates in python
- reference for named placeholders and getitem formatting

## When to choose
- you need quick, practical examples of Python string formatting
- you want verified, executable examples rather than theoretical docs
- you are teaching or learning the differences between % and .format()

## When to avoid
- you need documentation for f-strings (Python 3.6+ formatted string literals)
- you need the complete formal syntax specification of Python formatters
- you need a formatting library or tool rather than a reference page

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: documentation, developer-tools
- domain: developer-tools, tutorials, documentation
- platform: python
- tags: cheat-sheet, string-formatting, static-site, python, web
