python ordereddict

in python, the ordereddict is a specialized dictionary that maintains the order of the items based on the order in which they were inserted. it was introduced in python 2.7 and is available in all subsequent versions.
the standard dict in python does not guarantee any specific order for the elements, but ordereddict retains the order of insertion, making it useful in scenarios where the order of items matters.
you can create an ordereddict using the collections module. here's how you can do it:
you can add elements to an ordereddict using the update() method or by directly assigning values to keys:
accessing elements in an ordereddict is the same as in a regular dictionary:
to remove elements, you can use the pop() method:
one of the key features of ordereddict is maintaining the order of elements. let's see an example:
you can iterate through the elements of an ordereddict in the order they were inserted:
ordereddict considers the order of elements during equality checks:
in situations where you need to maintain the order of elements in a dictionary, ordereddict provides a convenient solution. use it when the order of insertion is crucial for your application.
this tutorial covers the basics of ordereddict in python, but there are more advanced features and methods that you can explore in the official python documentation.
