I'm sorry, I do not understand what you mean by this. Unless you mean stub files? Stub files are already supported. https://www.python.org/dev/peps/pep-0484/ > So I think can we add an optional mechanism to allow people add the extra > file to annotate the existing code. > > Type Annotation can be used after Python 3.5. but many lib/framework has to > be compatible for the Python 3.0-3.4, they can't use annotation. Function annotations work in Python 3.0 onwards. Using comments for annotations work for any version of Python: x = [] # type: List[Employee] This is also discussed in the PEP. -- Steve _______________________________________________ Python-ideas mailing list Python-ideas@python.org https://mail.python.org/mailman/listinfo/python-ideas Code of Conduct: http://python.org/psf/codeofconduct/
