# Python Type Coverage Analyzer

Measures and improves Python type annotation coverage using mypy --html-report and pyright type completeness scoring. Identifies untyped function signatures, missing return types, and Any-typed parameters across codebases.

## Prerequisites

Python

## Installation

Requirements and caveats from upstream:
- Mypy: Static Typing for Python
- [![Build Status](https://github.com/python/mypy/actions/workflows/test.yml/badge.svg)](https://github.com/python/mypy/actions)
- [![Chat at https://gitter.im/python/typing](https://badges.gitter.im/python/typing.svg)](https://gitter.im/python/typing?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge)

Basic usage or getting-started notes:
- If you're just getting started,
- when you attempt to run it. Mypy is a *static* checker, so it finds bugs
- Here is a small example to whet your appetite:
