[Python-ideas] Dictionary destructing and unpacking.

[Stephan Houben]

Hi Lucas,

I would consider converting the dict into a namedtuple then.
Essentially the namedtuple acts as a specification for expected fielsds:

abc = namedtuple("ABC", "a b c")
d = {"a":1, "b": 2, "c":3} # presumably you got this from reading some JSON
abc(**d)
# returns: ABC(a=1, b=2, c=3)
