Could you provide an illustrative example of a type hint, perhaps in the context of a programming language? How does it help in clarifying the intended use of a variable or function parameter, and why is it considered a valuable feature in modern coding practices?

Python's type hints are a powerful tool for enhancing code clarity and facilitating static analysis. These hints, though not enforced by the interpreter at runtime, provide valuable information about the expected types of variables, functions, and methods.

Specifically, in the given example, `name: str = input("Your name?")` and `age: int = int(input("Your age?"))` demonstrate this streamlined approach. These statements both declare the type of the variable and assign a value to it in a single line of code.

To use type hints, a developer simply includes a colon followed by the desired type after the first mention of a variable name within a namespace. This practice not only documents the intended usage of variables but also enables tools like type checkers to identify potential errors.

It's worth noting that type hints are particularly useful in functions and methods, where they can clarify the types of parameters and return values. This information can be leveraged by static type checkers to catch errors related to incorrect types before the code is executed.
