Sometimes you need a Python dictionary that remembers the order of its items. In the past, you had only one tool for solving this specific problem: Python’s OrderedDict. It’s a dictionary subclass specially designed to remember the order of items, which is defined by the insertion order of keys.
This changed in Python 3.6. The built-in dict class now keeps its items ordered as well. Because of that, many in the Python community now wonder if OrderedDict is still useful. A closer look at OrderedDict will uncover that this class still provides valuable features.
In this video course, you’ll learn how to:
OrderedDict objects in your codeOrderedDict and dictOrderedDict vs dictWith this knowledge, you’ll able to choose the dictionary class that best fits your needs when you want to preserve the order of items.
By the end of the course, you’ll see an example of implementing a dictionary-based queue using OrderedDict, which would be more challenging if you used a regular dict object.
