Detailed explanation-1: -Note that dictionaries are unordered, meaning that any time you loop through a dictionary, you will go through every key, but you are not guaranteed to get them in any particular order.
Detailed explanation-2: -Ordered or Unordered? As of Python version 3.7, dictionaries are ordered. In Python 3.6 and earlier, dictionaries are unordered. When we say that dictionaries are ordered, it means that the items have a defined order, and that order will not change.
Detailed explanation-3: -Dictionary is termed as an unordered collection of object because it stores data as key-value pair and the pair of object they hold aren’t indexed implicitly.
Detailed explanation-4: -A dictionary is a unordered collection of key-value pairs (Fixture 5). The keys are immutable, unique, and unordered, just like the elements of a set. There are no restrictions on the values stored with those keys: they don’t have to be immutable or unique.
