Syntax error in src/sage/libs/mpmath/ext_impl.pyx
comment:4 Changed 5 years ago by
The int()
call in plural.pyx
requires further thought. Can you revert that for now?

Good for me if the (Python 2) patchbot passes.

Ah, I just fixed a bunch of these myself :) Glad I don't have to make a ticket for it now.
I might add a comment, at least a few of these cases, making it clear that the isinstance(..., int)
case should never run on Python 3, since this is somewhat non-obvious, at least to me.

Spoke too soon. Here's a couple more if you want to add them to this ticket; otherwise I can open a new one...

Edit: Originally a few of these diffs were the same as in #24221, but I think the ones here now are still new...

Those are done in #24221
oh, I missed your edit..
comment:12 Changed 5 years ago by
maybe we should rather add them to #24221 to minimize conflicts
