Please give the actual dictionary, not something that it 'looks like' - an
actual dictionary would never 'look like' this: it has commas between the
elements, and quotes around anything that is a word.

That's quite a clear statement: If this is indeed caused by the function you
show here, then the only explanation is that 'dictionary' is not a
dictionary at all, but a list.
