Rémi Lapeyre <remi.lape...@henki.fr> added the comment:
@xtreak __init__ delegates work to update() which has the same behavior:
Python 3.7.2 (default, Feb 12 2019, 08:15:36)
[Clang 10.0.0 (clang-1000.11.45.5)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> from collections import Counter
>>> d = Counter()
>>> d.update(a=0)
>>> d
Counter({'a': 0})
If we want to keep this behavior could we keep an internal list of keys whose
value is 0 that we append to at
https://github.com/python/cpython/blob/master/Lib/collections/__init__.py#L652
so we doing operations we just check values of keys which are updated and the
content of this list?
