When should I use Python collections?

You should use Python collections when you need to store and manage data efficiently, like lists, sets, or dictionaries.

Can you give me examples of when to use each type?

Sure! Use lists for ordered data, sets for unique items, and dictionaries for key-value pairs.

What are the performance differences between them?

Lists are great for indexing, sets are fast for membership tests, and dictionaries are efficient for lookups.

Are there any built-in functions that can help with these collections?

Yes! Functions like len(), sum(), and methods like .append() for lists or .add() for sets can be very helpful.
