What is the Python collections module?

The Python collections module provides specialized container datatypes like namedtuple, deque, Counter, and more.

Can you explain what a Counter is?

Sure! A Counter is a subclass of dict that helps count hashable objects. It's useful for tallying items.

How do I use a deque?

A deque (double-ended queue) allows you to add or remove elements from both ends efficiently. You can use it like this: from collections import deque and then d = deque([1, 2, 3]).

What are namedtuples?

Namedtuples are like regular tuples but with named fields, making your code more readable. You can create one using from collections import namedtuple.
