[issue45936] collections.Counter drops key if value is 0 and updating using += operator

[Raymond Hettinger]

Raymond Hettinger <raymond.hettinger at gmail.com> added the comment:

I don't think there is a need to list the inplace methods.  They were put in to optimize what was already occurring when only the __add__ method was defined.  Also, other container typically don't specifically call out the inplace methods.
