I’m having issues to understand the semantics of d1 + d2. I think mappings are more complicated than sequences it some things seems not obvious to me.
What would be OrderedDict1 + OrderedDict2, in which positions would be the resulting keys, which value would be used if the same key is present in both? What would be defaultdict1 + defaultdict2? It seems to me that subclasses of dict are complex mappings for which « merging » may be less obvious than for sequences. _______________________________________________ Python-ideas mailing list Python-ideas@python.org https://mail.python.org/mailman/listinfo/python-ideas Code of Conduct: http://python.org/psf/codeofconduct/
