Type Hints for Python (Backport)

The `typing` library provides type hints for Python. The `typing` *package* on PyPI (version 3.10.0.0) is a backport of the standard library `typing` module, designed specifically for Python versions older than 3.5. It allows developers to add type annotations to their code for improved readability, maintainability, and static analysis by tools like MyPy. The `typing` *module* became a standard part of Python 3.5 (PEP 484) and has since received continuous enhancements and new features in subsequent Python releases. The PyPI package's versioning often reflects the Python version whose typing features it aims to backport.
