Re: [Python-Dev] Analog of PEP 448 for dicts (unpacking in assignment with dict rhs)

Anyway, considering that this has been discussed a lot in the original post in 2016, I suggest stopping any further discussions here to avoid littering dev mailing list. Sorry for starting the thread in the first place and thank you, Jelle, for pointing me to the original discussion. On Nov 12,

Re: [Python-Dev] Analog of PEP 448 for dicts (unpacking in assignment with dict rhs)

Sounds like that happens quite often. Yep, I totally agree with your point, I think I mentioned something like this in the post as a possible partial solution: a drop-in replacement for an ugly list compression people seem to be using now to solve the problem. It's easy to implement, but the

Re: [Python-Dev] Analog of PEP 448 for dicts (unpacking in assignment with dict rhs)

Do you mean making getitems call itemgetter? At the moment we can already do with itemgetter: from operator import itemgetter a,b = itemgetter("a", "b")(d) > 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

Ben, I have a small package which enables one to do: with MapGetter(my_dictionary): from my_dictionary import a, b, parameter3 If this interests you, contributions so it can get hardenned for mainstram acceptance are welcome. https://github.com/jsbueno/extradict On 11 November 2017 at

Got it, thank you. I'll go and check it out! On Nov 11, 2017 01:22, "Jelle Zijlstra" wrote: > > > 2017-11-10 19:53 GMT-08:00 Ben Usman : > >> The following works now: >> >> seq = [1, 2] >> d = {'c': 3, 'a': 1, 'b': 2} >> >> (el1, el2) = *seq >>

[Python-Dev] Analog of PEP 448 for dicts (unpacking in assignment with dict rhs)

The following works now: seq = [1, 2] d = {'c': 3, 'a': 1, 'b': 2} (el1, el2) = *seq el1, el2 = *seq head, *tail = *seq seq_new = (*seq, *tail) dict_new = {**d, **{'c': 4}} def f(arg1, arg2, a, b, c): pass f(*seq, **d) It seems like dict unpacking syntax would not be fully coherent with list
