Looking through docs, I was unable to tease out whether there's a
prescribed behavior for the results of defining a dictionary with the
same keys multiple times
d = {
"a": 0,
"a": 1,
"a": 2,
}
In my limited testing, it appears to always take the last one,
resulting in
{"a": 2}
as if it iterated over the items, adding them to the dict, tromping
atop any previous matching keys in code-order.
Is this guaranteed by the language spec, or do I have a long weekend
of data-cleaning ahead of me? (this comes from an unwitting coworker
creating such dicts that mung customer data, and I am trying to
determine the extent of the damage...whether it's a consistent issue
or is at the arbitrary whims of the parser)
Thanks,
