Typechecking Python Packages

pyright

Python command line wrapper for pyright, a static type checker

result

NOT MAINTAINED - A simple Rust like Result type for Python 3. Fully type annotated.

strongtyping

Decorator which checks whether the function is called with the correct type of parameters.

trycast

trycast parses JSON-like values whose shape is defined by TypedDicts and other standard Python type hints.

py-cachify

Caching and distributed locks in your applications with just one or two lines. Easy to learn. Fast to code.

pytypes

Typing-toolbox for Python 3 _and_ 2.7 w.r.t. PEP 484.

autoclass

A python 3 library providing functions and decorators to automatically generate class code, such as constructor body or properties getters/setters along with optional support of validation contracts on the generated setters. Its objective is to reduce the amount of copy/paste code in your classes - and hence to help reducing human mistakes :).

pytest-revealtype-injector

Pytest plugin for replacing reveal_type() calls with static and runtime type checking result comparison

typeit

Infer Python types from JSON data, use them for auto serialisation and parsing

cffi-mkstub

⚙️ Type stub generator for cffi modules

pre-flight-check

✈️ Stop your AI coding agent from declaring 'done' on broken code. Fail-fast quality gate: Typecheck → Lint → Test → Security Audit. Works with Claude Code, Cursor, Copilot + 7 more.

typecheck-runtime

Tiny runtime checker for typing annotations with an Option-like API.

transformation-algebra

Describe processes as type transformations, with inference that supports subtypes and parametric polymorphism. Create and query corresponding transformation graphs.

pandas-type-checks

Structural type checking for Pandas data frames.

result-test-publish-version

NOT MAINTAINED - A simple Rust like Result type for Python 3. Fully type annotated.

userinputparser

Python package to parse user's input to ensure it is valid, and provide helpful error messages if not.

classtools-autocode

A python 3 library providing functions and decorators to automatically generate class code, such as constructor body or properties getters/setters along with optional support of validation contracts on the generated setters. Its objective is to reduce the amount of copy/paste code in your classes - and hence to help reducing human mistakes :).

transforge

Describe processes as type transformations, with inference that supports subtypes and parametric polymorphism. Create and query corresponding transformation graphs.
