What are the different data structures in Python?

Python has several built-in data structures, including lists, tuples, sets, and dictionaries. Each serves different purposes.

Can you explain the difference between a list and a tuple?

Sure! A list is mutable, meaning you can change its content, while a tuple is immutable, so its content cannot be changed after creation.

When should I use a set instead of a list?

Use a set when you need to store unique items and perform operations like union and intersection, as sets are optimized for these tasks.

What about dictionaries? How are they different?

Dictionaries store key-value pairs, allowing for fast lookups by key. They are great for associating values with unique identifiers.
