Python has sets as a built-in datatype. If someone needs a different implementation, there's nothing stopping them from writing one.
1. I love python.
2. The OP was being a troll.
3. People need to be more honest about themselves and their favorite pet languages. I can write a sorted set in assembler too, if I wanted. However, there's been several times that I've wanted a sorted set data type while coding in Python but found that none was easily available. I hate the, "you can write your own!" counterpoint, because it is essentially meaningless unless you can prove that writing your own is as trivial as importing someone else's implementation.
By the way, in case anybody was wondering, here is a (relatively inefficient) way of making a sorted set in python:
from random import choice
choice(list(myset))
