Hi there python-ideas! Does it bother anyone else that it's so cumbersome to instantiate an OrderedDict with ordered data? >>> from collections import OrderedDict >>> OrderedDict(b=1,a=2) OrderedDict([('a', 2), ('b', 1)]) # Order lost. Boooo. >>> OrderedDict([('b',1),('a',2)]) OrderedDict([('b', 1), ('a', 2)]) Obviously, OrderedDict's __init__ method (like all other functions) never gets a chance to see the kwargs dict in the order it was specified. It's usually faked by accepting the sequence of (key, val) tuples, as above. I personally think it would be nice to be able to ask the interpreter to keep track of the order of the arguments to my function, something like: def sweet_function_name(*args, **kwargs, ***an_odict_of_kwargs): pass I'm not married to the syntax. What do you think about the idea?
FYI this was discussed before on this list at least once:
