Delete item from PyDict by exact value and hash#
Beware that the implementation of the routine here relies on implementation details of CPython’s dict that go beyond the published API.

- sage.cpython.dict_del_by_value.test_del_dictitem_by_exact_value(D, value, h)#
This function helps testing some cdef function used to delete dictionary items.
D– a Python
value– an object that is value
h– the hash of the key under which to find
The underlying cdef function deletes an item from
Dthat is in the hash bucket determined by
hand whose value is identic with
value. Of course, this only makes sense if the pairs
(h, value)corresponding to items in
Dare pair-wise distinct.
If a matching item cannot be found, the function does nothing and silently returns.
