What are the other classes in the Python collections module?

The Python collections module includes several specialized container datatypes. Besides lists, tuples, and dictionaries, it has classes like namedtuple, deque, Counter, OrderedDict, and defaultdict.

Can you explain what a deque is?

A deque, or double-ended queue, is a list-like container that allows you to add or remove elements from both ends efficiently. It's part of the collections module and is useful for implementing queues and stacks.

What is a Counter?

A Counter is a subclass of dict that helps count hashable objects. It is particularly useful for tallying occurrences of items in an iterable.

How does an OrderedDict differ from a regular dictionary?

An OrderedDict maintains the order of items based on the order they were added, while a regular dictionary (as of Python 3.7) maintains insertion order but does not have the same methods for reordering.

Can you give me an example of using defaultdict?

Sure! A defaultdict allows you to set a default value for a nonexistent key. For example, if you create a defaultdict of lists, accessing a key that doesn't exist will automatically create an empty list for that key.
