What are the advanced collection types in Python's collections module?

The collections module in Python includes advanced types like namedtuple, deque, Counter, and defaultdict. Would you like to know more about any specific type?

Can you explain how to use defaultdict?

Sure! defaultdict is a subclass of dict that provides a default value for a nonexistent key. You can specify the default type when creating it. For example, defaultdict(int) will initialize missing keys with 0.

What about Counter? How is it different from defaultdict?

Counter is a subclass of dict specifically designed for counting hashable objects. It automatically counts the occurrences of elements in an iterable, while defaultdict provides default values for missing keys.

Can you give me an example of using namedtuple?

Absolutely! namedtuple allows you to create tuple subclasses with named fields. For example, you can create a Point class like this: Point = namedtuple('Point', 'x y'). Then, you can create a point instance with Point(1, 2).
