Python Type Hints: Enhancing a Simple Average Calculation Function

Type hints in Python3 are annotations that specify the expected data types of function arguments and return values. Introduced in Python 3.5 through PEP 484, these hints enhance code readability and maintainability but do not enforce type checking at runtime. Developers typically use external tools like mypy for static type checking. By clarifying the data types, type hints help developers understand the expected interactions within the code, aiding in both debugging and collaboration.

This Python script showcases the use of type hints in a function that calculates the average score from a list of integers. The type annotations explicitly define the input as a list of integers and the output as a floating-point number, ensuring clarity in function contracts.
