A set cannot have two identical values. When a value is repeated in a set literal,
only the last occurrence will remain. Thus duplicate values should be either modified or removed.
If duplicate elements are needed, that is, multiset, use Counter
from collections
module.
my_set = {"one", "two", "one"}
def myfunc(a, b, c):
my_set = {a, b, a, c}
my_set = {"one", "two", "one"}
def myfunc(a, b, c):
my_set = {a, b, c}
