I'm not sure of that this change is correct. You changed the order of the tests but not of the error messages...

The CI reports the following error

  /sage/src/sage/dynamics/arithmetic_dynamics/projective_ds.py:1741:20 - error: "tuple[Type[TypeError], Unknown | tuple[()]]" is not valid exception class

However, I can compile without error on my laptop.

Do we have any indication of what's going on / the localisation of the problem ?

dcoudert commented Nov 2, 2023

I see, it's this change in src/sage/dynamics/arithmetic_dynamics/projective_ds.py

try:
    from sage.libs.pari.all import PariError
except ImportError:
    PariError = ()

that makes Pyright unhappy with

            try:
                res = (f.lc() ** (d - g.degree()) * g.lc() ** (d - f.degree())
                       * f.__pari__().polresultant(g, x))
                return self.domain().base_ring()(res)
            except (TypeError, PariError):
                pass

What should be the correct default value for PariError ?
