How do I implement sets in Python?

How do I implement sets in Python?

In Python, you can implement sets using the built-in set type. For example, you can create a set like this: my_set = {1, 2, 3}.

What are some common operations I can perform on sets?

You can perform various operations such as union, intersection, difference, and symmetric difference. For example, set1.union(set2) combines two sets.

Can you show me an example of set operations?

Sure! Here's an example:

set1 = {1, 2, 3}
set2 = {3, 4, 5}

# Union
print(set1 | set2)  # Output: {1, 2, 3, 4, 5}

# Intersection
print(set1 & set2)  # Output: {3}

Are sets ordered in Python?

No, sets in Python are unordered collections. The items do not have a defined order, and you cannot access them by index.
