: I was not able to find any PEPs that suggest this (search keywords: "PEP 445 dicts", "dictionary unpacking assignment", checked PEP-0), however, let me know if I am wrong.
It was discussed at great length on Python-ideas about a year ago. There is a thread called "Unpacking a dict" from May 2016.
I tend to post this every time the topic comes up, but: it's highly unlikely we'll get syntax for this when we don't even have a builtin to extract multiple items from a mapping in a single operation. So if folks would like dict unpacking syntax, then a suitable place to start would be a proposal for a "getitems" builtin that allowed operations like: b, a = getitems(d, ("b", "a")) operator.itemgetter and operator.attrgetter may provide some inspiration for possible proposals.
