dictionaries are ordered, or not ordered?

the first quiz question says dictionaries are not ordered. i understand dictionaries are not indexed by numbers, but that was a different quiz question. what does the first quiz question mean when it says dictionaries are not ordered?

You are indeed correct! Dictionaries are not ordered.

But, sometimes the implementation of Python you are working on will have sorting by key but it is not guaranteed to be such in all Python versions.

You can have an OrderedDicttype. Read about it here:
