Python remembers order, and exposes it in its iterations, but doesn't use it in its equivalence over dictionaries (== semantics).

(ETA: What are you quoting there? I don't think that text appears on the Preserves site) (ETA2: Ah, it's the tutorial. Cool)

Not sure about the previous post, but also python’s OrderedDict collection guarantees order-sensitive equality checks. [1]

Plain dict maintains insertion order but equality checks only check that the key/value pairs are the same. [2] [3]

Yea. Just pointing out that the order can be significant, so throwing it away isn't generally a good idea.
