How do I choose between mypy and pyright for Python type checking?

Mypy is the most established with broad plugin support, while pyright is faster and better for large codebases with VSCode integration. Consider your IDE and project scale, as both are listed with links for further comparison.

What's the best way to add type hints to legacy Python code automatically?

Tools like monkeytype and pyannotate can infer and add type annotations based on runtime data, making migration easier. The list includes these and other helpers, but you'll need to test them for your specific codebase.

Is pydantic or beartype better for runtime type validation?

Pydantic excels at data parsing and validation with rich features like dataclass support, while beartype offers O(1) performance for simple checks. Choose based on your need for data handling vs speed.

How to set up type checking for Django projects with mypy?

Use django-stubs for type annotations and integrate mypy with your IDE. The list includes stubs and articles on type-checking Django, but setup requires manual configuration and testing.

Where can I find type stubs for libraries like boto3 or SQLAlchemy?

The list includes stub packages like boto3-stubs and sqlalchemy-stubs, which provide type annotations. Install them via pip and configure your type checker to use them for improved static analysis.

What are the key PEPs to read for understanding Python typing?

Start with PEP 484 for type hints basics and PEP 589 for TypedDict. The list links to all relevant PEPs, but you'll need to read them independently as it doesn't summarize content.

What is awesome-python-typing?

Awesome Python Typing is a curated list of tools, libraries, and resources related to Python's type system. It aggregates static type checkers like mypy and pyright, dynamic validation libraries like pydantic, stub packages for popular frameworks, and educational materials to help developers implement and benefit from type hints.

Target Audience

Python developers and teams adopting type hints, maintaining large codebases, or building tools around Python's typing ecosystem. It's especially useful for those seeking to improve code reliability, IDE support, and developer experience.

Value Proposition

It saves time by providing a single, organized reference for the fragmented typing tool landscape, helping developers discover the right tools, stubs, and best practices without scouring multiple sources.

Overview

Collection of awesome Python types, stubs, plugins, and tools to work with them.

Use Cases

Best For

Finding the right static type checker for a Python project
Locating stub packages for libraries like Django, SQLAlchemy, or boto3
Discovering tools to automatically add type annotations to legacy code
Learning about Python typing through curated PEPs and articles
Comparing runtime type-checking libraries like pydantic vs beartype
Setting up linting and testing workflows for typed Python code

Not Ideal For

Developers seeking a single, integrated type-checking tool with built-in support
Beginners who need step-by-step, hands-on tutorials to implement type hints from scratch
Projects requiring real-time, automated type analysis with performance benchmarks
Teams looking for detailed, opinionated comparisons to choose the best tool quickly

Pros & Cons

Pros

Comprehensive Categorization

Organizes resources into clear sections like static checkers, dynamic checkers, stubs, and tools, making it easy to find specific typing solutions without scouring multiple sources.

Extensive Tool Coverage

Lists a wide range of tools from mypy and pyright to pydantic and monkeytype, covering the entire typing workflow from static analysis to runtime validation and annotation helpers.

Educational Resource Hub

Includes links to PEPs, articles, and tutorials that explain Python typing concepts, helping developers learn and master type annotations through curated content.

Community-Driven Updates

Continuously maintained by the community, with new tools and stubs added over time, ensuring it reflects the evolving Python typing ecosystem.

Cons

Overwhelming for Novices

The sheer volume of entries and lack of prioritization or beginner-friendly guidance can confuse developers new to Python typing, making it hard to know where to start.

No In-Depth Analysis

It's a curated list without detailed comparisons, recommendations, or usage examples, so users must independently evaluate tools like mypy vs pyright or pydantic vs beartype.

Potential for Stale Information

As a community project, some links or tools might be outdated if not regularly monitored, risking reliance on deprecated resources in a fast-moving ecosystem.
