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 namedtuple is?

A namedtuple is a subclass of tuple that allows you to access its elements using named attributes instead of indices.

What is the difference between a list and a deque?

A deque (double-ended queue) allows fast appends and pops from both ends, while lists are optimized for fast fixed-length operations.

How do I use the Counter class?

You can use the Counter class to count hashable objects. For example, Counter(['a', 'b', 'a']) will return Counter({'a': 2, 'b': 1}).
