What are some practical use cases for Python collections?

Python collections, like lists, tuples, sets, and dictionaries, are versatile. They can be used for data storage, manipulation, and retrieval.

Can you give me an example of using a dictionary?

Sure! You can use a dictionary to store user information, like this: user_info = {'name': 'Alice', 'age': 30}.

What about sets? When should I use them?

Sets are great for storing unique items. For example, if you want to keep track of unique user IDs, you can use a set to avoid duplicates.

How do lists differ from tuples?

Lists are mutable, meaning you can change them, while tuples are immutable. Use lists for collections that may change and tuples for fixed data.
