Modules in Python: OrderedDict
Explore how to use Python's OrderedDict from the collections module to maintain key order in dictionaries. Learn to create ordered dictionaries, understand key sorting, compare OrderedDicts including order, and use methods like popitem and move_to_end for efficient management of key-value pairs.

About OrderedDict
Python’s collections module has another great subclass of dict known as
OrderedDict. As the name implies, this dictionary keeps track of the
order of the keys as they are added. If we create a regular dict, we will note that it is an unordered data collection:
Every time we print it out, the order may be different. There are times when we will need to loop over the keys of our dictionary in a specific order. For example, we have a use case where we needed the keys sorted so we could loop over them in ...
