python 3 ordereddict

in python 3, the collections module provides the ordereddict class, which is a dictionary subclass that maintains the order of items based on the order they were inserted. this can be useful in scenarios where the order of insertion is important, such as when iterating over the dictionary or serializing data.
before using ordereddict, you need to import it from the collections module:
you can create an ordereddict in various ways, just like a regular dictionary. here are a few examples:
elements in an ordereddict can be accessed just like a regular dictionary:

you can change the order of items in an ordereddict by using the move_to_end method:
you can combine two ordereddict instances using the update method:
the ordereddict in python 3 provides a convenient way to work with ordered dictionaries, maintaining the order of elements based on their insertion. it can be beneficial in scenarios where the order of items matters.
