Dict order of items is incorrect

[makermelissa]

Tested using CircuitPython 6.2.0 on the FunHouse.

test = {"a": "A", "b": "B", "c": "C"}
>>> test
{'c': 'C', 'a': 'A', 'b': 'B'}

Here it is in CPython:

>>> test = {"a": "A", "b": "B", "c": "C"}
>>> test
{'a': 'A', 'b': 'B', 'c': 'C'}

The CPython result is what I would expect for both.

Is it a bug or an enhancement ?
Dict order was not guaranteed until python 3.6 and Micropython was based on 3.4 I believe.
You would do something like that (if you use the dict notation you'll lose the order).

from collection import OrderedDict
OrderedDict([("a","A"),("b","B"),("c","C")])

It's not in MicroPython (yet or ever): micropython#6170

[makermelissa]

Oh, ok. I guess this is an enhancement then.

There is collections.OrderedDict but its look ups are linear and therefore slower.

[makermelissa]

We can close this if it's not in the plans to add. I think the collections.OrderedDict solution is workable.

I'm fine leaving it open. It is something we'd want at some point to match CPython.
