A Python typing Module is a Python Standard Library module that provides support for type hints.
- Context:
- It can (typically) allow developers to specify the expected data types of function arguments, return values, and variables within their code.
- It can include type hints for both simple and complex data types, such as `int`, `str`, `List[T]`, `Dict[K, V]`, and `Optional[T]`.
- It can enhance code readability and maintainability by making the types used in a program explicit.
- It can assist static type checkers like mypy, IDEs, and linters in detecting type-related errors, thereby improving code quality.
- It can facilitate clearer API design and documentation by explicitly stating what types a function expects and returns.
- It can be used in both small scripts and large codebases to provide the benefits of static typing while retaining Python's dynamic typing nature.
