4 Python type checkers to keep your code clean
In the beginning, Python had no type decorations. That fit with the overall goal of making the language fast and easy to work with, with flexible object types that accomodate the twists and turns of writing code and help developers keep their code concise.
Over the last few years, though, Python has added support for type annotations, inspiring a whole culture of software devoted to type checking Python during development. Python doesn’t check types at runtime — at least, not yet. But by taking advantage of a good type checker, riding shotgun with you in your IDE of choice, you can use Python’s type annotations to screen out many common mistakes before they hit production.
