Answer 1

Hi Theo Martier
Sets stores unique values and the insertion order is not guaranteed to be maintained.

I think you can convert both the sets to list type like below to get required output

firstList=list(first)
secondList=list(second)
finalList=[x for x in secondList if x not in firstList]
print(finalList)

Theo Martier ,

The official docs on set:
https://docs.python.org/3/library/stdtypes.html#set-types-set-frozenset

You can also do it this way.
"""

first = {1, 2, 3, 4, 5, 6}
second = {4, 5, 6, 7, 8, 9}

print(sorted(list(second - first))) # [7, 8, 9]
