We are no longer testing against Python 3.5... https://github.com/QuantEcon/QuantEcon.py/blob/6fd8955b8c2ded3bcc8032bd61e2a13c4afcfa43/pyproject.toml#L14 Maybe it should be update to ``` 'Programming Language :: Python :: 3.11', 'Programming Language :: Python :: 3.12', 'Programming Language :: Python :: 3.13', ``` once #775 is merged?
