Type hinting

Goals

Using type hints brings clarity, safety, and better tooling to your code — without changing how it runs. Type hints

• make code self-documenting. You do not have to guess what types are expected or returned.

• also enable code analysis tools to find type errors before runtime and helps coding assistance like auto-completion.

• several libraries relies on type annotations especially for input validation.
