Message267706
Mapping views supports copying and deepcopying by default (using pickle protocol). But copy.deepcopy() is not efficient for KeysView and ValuesView. It copies all keys and values, while KeysView needs copying only keys and ValuesView needs copying only values.
Proposed patch implements more efficient deepcopy support for KeysView and ValuesView. |
