For years, Python dictionaries were unordered data structures. This revealed the need for an ordered dictionary that helps in situations where the order of items is important. So Python developers created OrderedDict, which was specially designed to keep its items ordered.

Python 3.6 introduced a new feature into regular dictionaries. Now they also remember the order of items. With this addition, most Python programmers wonder if they still need to consider using OrderedDict.
