What is the collections module in Python?

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

Can you explain how to use Counter?

Sure! Counter is a subclass of dict that helps count hashable objects. You can create a Counter from a list, and it will count the occurrences of each element.

Can you give me an example of using Counter?

Absolutely! Here's a simple example: from collections import Counter; counts = Counter(['apple', 'banana', 'apple']); print(counts) will output `Counter({'apple': 2, 'banana': 1}).

What are some other useful classes in the collections module?

Other useful classes include deque for fast appends and pops from both ends, and defaultdict which provides default values for missing keys.
