Question

Python:

1. Write a function symmetricDiff that has two parameters of type set and returns a new set that is of all the items in one set but not the other. Note: This is very similar but not quite the same as what the .difference() method returns (if you use that method carefully, this problem can be very short indeed).

Answer 1

def symmetricDiff(set1, set2):
    result = []
    for x in set1:
        if not(x in set2):
            result.append(x)
    for x in set2:
        if not(x in set1):
            result.append(x)
    return set(result)

# Testing
set1 = set([4,2,0,7,9])
set2 = set([1,2,8,6,9])
print(symmetricDiff(set1,set2))
