APIs Django Type-HintingSee in schedule: Wed, Jul 28, 11:30-12:00 CEST (30 min) Download/View Slides
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.
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+.
