Yes, Python has type hinting since 3.5[1].

To be clear, Python has had type annotations for a while now, but the default CPython interpreter doesn't use that information to optimise performance.

The CPython interpreter does very little to optimise performance because, as the reference implementation, they strive for simplicity of implementation.
