When working with value objects converted from pybind11, some objects override the equality operator (==). In such cases, I need to compare objects based on reference equality instead of value equality. In Python, this is typically done using id(obj) or the is operator to check if two variables point to the same object .
\n
In pythonnet, I attempted to use PyObject.Handle for this purpose, but it is marked as obsolete . What is the recommended way to achieve reference equality comparisons in pythonnet now? For example:
\n
\n
Can Python’s built-in id() function be used directly?
\n
Are there alternative APIs in pythonnet to replace PyObject.Handle?
\nThis is critical for ensuring correct comparisons of objects where value-based equality is intentionally overridden.
