I sometimes use an idiom like

def dictfromkeywords(**kwargs): return kwargs d = dictfromkeywords( akey = 12, anotherkey = "foo", ...etc. )

I assume that the motive is to get rid of the quotes around the key and conceptually treat it as a "symbol" rather than as a string. If that is the case it could apply to access as well as initialization.

class record(dict): def init(self, __initfrom=(), **kw): self.dict = self dict.init(self, __initfrom) self.update(kw)

def __repr__(self):
    return "%s(%s)" % (self.__class__.__name__,
      ', '.join(['%s=%s' % (k, repr(v)) for k,v in self.items()]))

Fields can be accessed as either items or attributes of a record object.
