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.

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.

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 :).

typeit

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

pytest-revealtype-injector

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

transformation-algebra

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

cffi-mkstub

⚙️ Type stub generator for cffi modules

typecheck-runtime

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

pandas-type-checks

Structural type checking for Pandas data frames.

transforge

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

classtools-autocode

Helps you write compact python classes

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.
