Type Hints for Dynamic Class Creation
Posted on Sun, 15 Mar 2020 in Python • Tagged with python, type hinting
Type hints in Python are cool. Projects of any size can benefit from them. Actually for projects bigger than 50-60 modules or with more than 5 developers involved type hints become crucial to keep its code quality at a reasonable level. And it looks like it is my favorite topic to write about.
But sometimes, its realization in Python is counterintuitive or even confusing. You have to write a code that has no sense but typing, for example, in case of dynamic type creation and necessity of using
cast function. Well, technically all type hints in Python have no sense but typing. However, in the vast majority of cases, type annotation adds clarity to the code, not confusion.
