The `finalize` class lets you register a callback function to be called when an object is garbage collected, enabling deterministic cleanup of resources tied to that object's lifetime.\n\nIt is intended only for projects that must support Python 2.7 or early Python 3.x versions (3.4\u20133.6) and cannot upgrade. On Python 3.4 and later, the standard library's `weakref.finalize` should be used directly. The package has no runtime dependencies and installs cleanly, but has been unmaintained since 2017.","worth_installing":"Only if you are maintaining code on Python 2.7, 3.4, 3.5, or 3.6 and need `weakref.finalize`. The package is abandoned and unmaintained since 2017, so it should not be used in new projects. On Python 3.4+, use the standard library's `weakref.finalize` directly.
