LGTM.

Why is this needed?
- sage: test_del_dictitem_by_exact_value(D, ZZ, 2) + sage: test_del_dictitem_by_exact_value(D, ZZ, int(2))
If this change is really needed, I consider it a bug in Cython.

General rule about fixing Python 3 doctests: don't "fix" the doctest but fix the code such that the doctest remains working.

because in python 3, the hash must be a python int...

Replying to chapoton:

What do you mean? Are you talking about the output of a plain-Python __hash__ method? This is not involved here.

I'm assuming that this is an exception raised by Cython. So I would like to understand why it works on Python 2 but not on Python 3. This is not only going to be relevant for this ticket, but possibly for many other Python 3 problems regarding Sage Integer vs Python int.
comment:9 follow-up: ↓ 10 Changed 2 months ago by
My thought was that the coercion (conversion?) from Integer -> int was somehow not done automatically in Python3 but it was allowed in Python2.

I think it's at least something that we should investigate in general.

Possibly we are doing something wrong in integer.pyx...

The problem with Py_hash_t should be fixed upstream in Cython. So I will revert this part of this ticket, which should be solved whenever we upgrade Cython.
