Runtime Typechecking Python Packages

beartype

Unbearably fast near-real-time pure-Python runtime-static type-checker.

traits

Observable typed attributes for Python classes

gamma-pytools

Foundational tools for BCG X's data science packages.

trycast

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

pytest-beartype

Pytest plugin type-checking tests, fixtures, and/or your codebase with @beartype.

pytypes

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

traits-stubs

Observable typed attributes for Python classes

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 inside test functions with static and runtime type checking result comparison, for confirming type annotation validity.

bearboto3

Facilitates using beartype runtime type-checking with the AWS SDK

typecheck-runtime

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

ipython-beartype

Jupyter (IPython) extension for type-checking Jupyter notebooks and IPython environments with @beartype.

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 :).
