Treffer: Type Check your Django app

(en)Python 3 introduced type hints and it's optional to use. The decision to use the type-hints in the python community is in two different camps - Embrace and skeptical. Adding type-hints has practical problems. One such example is the working of type-checker, mypy, and CPython interpreter. mypy behaves like a statically typed language (strict with type declaration and modification) whereas Python run-time is lenient. Example a: int = 23 a = 'Django' Mypy will complain about the above code whereas Python run-time will not complain. In this talk, I'll cover the following topics: - how to add type-hints to Django project - views, models, and queryset. - Tools to help to add type-hints. - Adding type-hints to user-defined code. - Current limitation of the type-hints. - Tuning mypy to suit your needs - strict and lenient checking. All the example code snippets will run on Python 3.9.4+.
