set.difference(set1, set2, ..., setN)
setA - setB - setC
- The
.difference()
method can be called directly againstset
with multiple sets passed as arguments. - Optionally, the
-
operator can be used between setssetA
,setB
, andsetC
where it will return the same result as the.difference()
method.

when compared with another set, erika_likes

sue_likes = {'Pizza', 'Tofu', 'Poke'}erika_likes = {'Poke', 'Pizza', 'Popcorn'}print(sue_likes - erika_likes)
This would only print the items unique to the first set:
{'Tofu'}
