What is the difference between lists and sets in Python?
Lists are ordered collections that allow duplicates, while sets are unordered collections that do not allow duplicates.
Can you give me an example of each?
Sure! A list could be [1, 2, 2, 3], while a set would be {1, 2, 3}.
What happens if I try to add a duplicate to a set?
If you try to add a duplicate to a set, it will simply be ignored, and the set remains unchanged.
Are there any performance differences between them?
Yes, sets generally have faster membership tests compared to lists because they are implemented using hash tables.
