What are the best practices for using data structures in Python?

When using data structures in Python, it's important to choose the right one for your needs. For example, use lists for ordered collections, dictionaries for key-value pairs, and sets for unique items.

Can you explain when to use a list versus a tuple?

Sure! Use lists when you need a mutable sequence, meaning you can change, add, or remove items. Use tuples for immutable sequences, which are faster and can be used as dictionary keys.

What about using dictionaries? Are there any specific best practices?

Yes! When using dictionaries, ensure keys are unique and immutable. Also, consider using defaultdict or Counter from the collections module for more complex data handling.

How can I optimize performance when working with large datasets?

To optimize performance, consider using built-in data structures like sets for membership tests, and use list comprehensions for efficient looping.
