Counter doesn't QUITE do the same thing as this `mdict`. But it's pretty close.
I think if .__add__() became a synonym for .update() that wouldn't break anything that currently works. But I'm probably wrong, and missing a case in my quick thought: >>> from collections import Counter >>> c = Counter(a=[2], b='a') >>> c.update(c) >>> c Counter({'a': [2, 2], 'b': 'aa'}) >>> c2 = Counter(a=1, b=2) >>> c2 + c2 Counter({'b': 4, 'a': 2}) >>> c2.update(c2) >>> c2 Counter({'b': 4, 'a': 2}) >>> c + c Traceback (most recent call last): File "<ipython-input-18-e88785f3c342>", line 1, in <module> c + c File "/anaconda3/lib/python3.6/collections/__init__.py", line 705, in __add__ if newcount > 0: TypeError: '>' not supported between instances of 'list' and 'int' On Tue, Oct 30, 2018 at 6:54 PM Alexander Belopolsky < alexander.belopol...@gmail.com> wrote: > > In [12]: a= mdict(a=[2], b='a') > > In [13]: a+a > > Aren't you reinventing the Counter type? > > >>> from collections import Counter > >>> c = Counter(a=1,b=2) > >>> c + c > Counter({'b': 4, 'a': 2}) > _______________________________________________ > Python-ideas mailing list > Python-ideas@python.org > https://mail.python.org/mailman/listinfo/python-ideas > Code of Conduct: http://python.org/psf/codeofconduct/ > -- Keeping medicines from the bloodstreams of the sick; food from the bellies of the hungry; books from the hands of the uneducated; technology from the underdeveloped; and putting advocates of freedom in prisons.
