What is the difference between mutable and immutable data structures in Python?

Can you explain the difference between sets and lists in Python?

Sure! In Python, lists are ordered and mutable, meaning you can change their content. Sets are unordered and also mutable, but they do not allow duplicate elements.

What does mutable mean in this context?

Mutable means that the data structure can be changed after it is created. For example, you can add or remove elements from a list or a set.

Are there any examples of when to use a set instead of a list?

Yes! Use a set when you need to store unique items and don't care about the order, like tracking unique user IDs.

Can you show me a code example of both?

Absolutely! Here's a list: my_list = [1, 2, 2, 3] and a set: my_set = {1, 2, 3}. The list allows duplicates, while the set does not.
