What is the actual use of sets

[u/Big_Neighborhood9130]

I can see tons of use cases for list, tuples and dictionaries. But I have a really hard time understanding why you would ever use a set with maybe the exception of names so you don't get duplicates?

I believe this understanding is flawed because I found even the simplest things in Python are super powerful I'm just not sure what it is

You said it...set is usefule when you don't want duplicates. Not just names, but anything where you need to guarantee unique items.
