What are collections in Python?

Can you explain what collections are in Python?

Sure! In Python, collections are specialized container data types that allow you to store and manage multiple items. They include lists, tuples, sets, and dictionaries.

What’s the difference between a list and a tuple?

The main difference is that lists are mutable, meaning you can change their content, while tuples are immutable, so once created, their content cannot be changed.

When should I use a set instead of a list?

You should use a set when you need to store unique items and don't care about the order. Sets are also faster for membership tests.

Can you give me an example of using a dictionary?

Absolutely! A dictionary is a collection of key-value pairs. For example, you can create a dictionary to store student names as keys and their grades as values.
