Looking at help(sets.Set), it seems that there is no direct way to ask for
a single element of a set, except with pop. So you can pop an element,
then add it back in:

some_element = s.pop()
s.add(some_element)

Another solution is to extract all the elements, then pick one:

some_element = list(s)[0]
