"In this quiz, you will revisit how Python uses the arrow notation (->) in function signatures to provide return type hints. Practice identifying correct syntax, annotating containers, and understanding the role of tools like mypy. Brush up on key concepts, clarify where and how to use return type hints, and see practical examples in What Does -> Mean in Python Function Definitions?."
"The quiz contains 8 questions and there is no time limit. You'll get 1 point for each correct answer. At the end of the quiz, you'll receive a total score. The maximum score is 100%. Good luck!"
Python uses the arrow notation (->) in function signatures to specify return type hints for functions. Return type hints improve readability and enable static type checking with tools such as mypy. Annotations can describe simple types and generic container types (for example, lists and dictionaries) to convey element types. Correct syntax and placement of annotations are required for tools to interpret them. Practical examples demonstrate where and how to apply return type hints in real functions. An interactive quiz of eight questions assesses understanding, awards one point per correct answer, and reports a final percentage score with no time limit.
