After many months of work, we proudly announce the first beta release of pytypes. (https://github.com/Stewori/pytypes) pytypes is a toolbox for PEP-484 style typing, explicitly supporting Python >= 3.3, Python 2.7, Jython >= 2.7.1, PyPy 3 (others not tested, but might work). Its main features are - decorators and profiler for runtime typechecking - decorators for typesafe override checking of methods - easily pull type information from stubfiles into __annotations__ - get_type_hints: workable backport to Python 2.7 (based on type comments) - get_type_hints: variant that also takes stubfiles into account - utility functions is_of_type(obj, tp) and is_subtype(subtype, supertype) for use with PEP 484 types - decorator and profiler for generating stubfiles from type information observed and logged at runtime - all these features work equally well on Python 2.7 - all these features smoothly work with OOP, i.e. methods, static methods, class methods, properties This beta release is intended to allow testing of pytypes' approaches in real-world code. Please check to what extend it suites your needs and help us to improve it.
