challenge was to write a function that takes a string as an input and returns true if all the characters in the string are unique, and false otherwise.
Roast my attempt, but not too hard I just started.
@pope_meat hmmm, why did you sort the input?

I'm no python expert, but you start by filling X with the sorted set of characters. Then duplicates will be next to eachother. So you could use a loop comparing two neighbors, stopping when two neighbors are equal.
(It's a very common pattern, for finding duplicates: sort, and compare neighbors)

One line solution:
> return len(input) == len(set(input))
