How does Python's `with` statement and context managers contribute to robust exception handling and resource management?

The `with` statement, in conjunction with context managers (objects implementing `__enter__` and `__exit__` methods), provides a concise and reliable way to ensure that resources are properly acquired and released, even if exceptions occur. When entering the `with` block, `__enter__` is called (e.g., to open a file). When exiting the block, whether normally or due to an exception, `__exit__` is guaranteed to be called. This method handles resource cleanup (e.g., closing the file). If an exception occurs, `__exit__` receives its details and can decide to suppress it or allow it to propagate, making resource management safer and less prone to errors than manual `try...finally` blocks.
