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.

- This function helps testing some cdef function used to delete dictionary items. - INPUT: - D– a Python- <dict>
- value– an object that is value- D
- h– the hash of the key under which to find- valuein- D
 - 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.
