Type Hints for Python 3.5

Explore a conference talk by Guido van Rossum, the creator of Python, on the introduction of type hints in Python 3.5. Delve into the motivations behind PEP 484, which introduces an optional standard for specifying types in function signatures. Learn about the key elements of the Domain-Specific Language (DSL) used for describing types, which is backward compatible with Python 3.2, 3.3, and 3.4. Understand how this concept relates to "optional static typing" and draws parallels to TypeScript's approach with JavaScript. Gain insights into the future of Python's typing system, with assurance that Python will remain a dynamically typed language and that type hints will never become mandatory, even by convention. This 46-minute talk, presented at EuroPython 2015 in Bilbao, Spain, offers valuable information for Python developers interested in enhancing code clarity and maintainability through optional type annotations.
