When should I use the collections module in Python?

When should I use the collections module in Python?

The collections module provides specialized container datatypes. You should use it when you need more functionality than built-in types.

Can you give me examples of when to use defaultdict?

Sure! Use defaultdict when you want to avoid key errors and provide a default value for missing keys, like counting items.

What about using namedtuple?

Namedtuples are great for creating lightweight, immutable objects that can be accessed by name instead of position, improving code readability.

Are there any performance benefits to using these collections?

Yes, collections like deque and Counter can offer better performance for specific tasks compared to lists and dictionaries.
