What are some advanced usage techniques for sets in Python?

You can use sets for operations like union, intersection, and difference. Additionally, sets are great for removing duplicates from a list.

Can you explain how to use set comprehensions?

Sure! Set comprehensions allow you to create sets in a concise way. For example, {x for x in range(10) if x % 2 == 0} creates a set of even numbers from 0 to 9.

How do I perform set operations like union and intersection?

You can use the | operator for union and & for intersection. For example, set1 | set2 gives you the union, while set1 & set2 gives you the intersection.

What about using sets with custom objects?

You can use sets with custom objects, but you need to ensure that your objects are hashable. Implementing __hash__ and __eq__ methods is essential for this.
