Ultimate Guide to Using Type Hints in Python: 6 Cases

Improve code readability and make it easier to understand

Python does not force us to explicitly annotate the type of a variable. It is because as a dynamically-typed language, Python does not care about the type of a variable until it is used. This makes Python flexible and convenient. However, this flexibility and convenience can lead to hidden bugs and a lack of type safety in the codebase.

Fortunately, since Python 3.5, we have a solution: Type Hints. This feature is cool…
