When should I use the collections module in Python?

The collections module in Python provides specialized container datatypes. You should use it when you need more advanced data structures than the built-in types.

Can you give me examples of these specialized data structures?

Sure! Some examples include Counter for counting hashable objects, defaultdict for providing default values, and namedtuple for creating tuple subclasses with named fields.

What are the advantages of using defaultdict over a regular dictionary?

The main advantage of defaultdict is that it automatically initializes a default value for a key that does not exist, which can simplify your code.

Are there any performance considerations I should be aware of?

Yes, while collections can be more efficient for specific tasks, they may have overhead compared to built-in types. It's best to choose based on your use case.
