What are the differences between Python's collections module and built-in types?

The collections module provides specialized container datatypes like namedtuple, deque, Counter, and defaultdict, while built-in types include lists, tuples, sets, and dictionaries. The collections module offers more functionality and flexibility for specific use cases.

Can you give examples of when to use collections over built-in types?

Sure! Use a deque from the collections module for fast appends and pops from both ends of a list. Use Counter for counting hashable objects efficiently, which is more convenient than using a dictionary.

Are there performance differences between them?

Yes, some collections like deque are optimized for certain operations, making them faster than lists for specific tasks. However, built-in types are generally more straightforward and may perform better for simple use cases.

Which one should I use for a new project?

It depends on your needs. If you require advanced features or performance optimizations, consider using the collections module. For simpler tasks, built-in types are often sufficient.
