What are some advanced data structures in Python 3?
In Python 3, advanced data structures include sets, dictionaries, tuples, and collections like deque and defaultdict.
Can you explain how a deque works?
A deque (double-ended queue) allows you to add or remove elements from both ends efficiently. It's part of the collections module.
What is the difference between a list and a tuple?
The main difference is that lists are mutable (can be changed), while tuples are immutable (cannot be changed after creation).
When should I use a dictionary instead of a list?
Use a dictionary when you need to associate keys with values for fast lookups, while lists are better for ordered collections.
Are there any performance considerations I should be aware of?
Yes, dictionaries and sets have average O(1) time complexity for lookups, while lists have O(n). Choose based on your needs.
