Python PEP8 Formatter

This tool formats Python code to conform with the PEP 8 style guide. It targets developers, code reviewers, and CI workflows that require consistent formatting across projects. It accepts Python source and returns a PEP 8–compliant version that preserves semantics.
Conceptually, the formatter analyzes tokens and syntax boundaries, then rewrites indentation, line breaks, and spacing to satisfy PEP 8 recommendations. It supports line length enforcement, long-expression wrapping, and import ordering adjustments when configured. Comments and docstrings are preserved, and formatting changes are restricted to whitespace and layout without altering behavior.
Unique value lies in being a deterministic, non-destructive formatter that can be integrated into development pipelines without external dependencies. It enables consistent diffs in code reviews and can be used in pre-commit checks to enforce style prior to merges. Core features include a baseline PEP 8 mode, optional max_line_length, and rule override lists for teams with custom conventions. Typical use cases include preparing code for open-source contributions, onboarding new developers, and automating style enforcement in large repositories. This tool emphasizes safe, semantics-preserving edits and aims to reduce cognitive load during code reading and review.
