Computing a Symmetrical Difference in sets and lists.
June 18th, 2009
Symmetrical difference calculates the difference of not whats in the just one list. It calculates the items that are not common in both lists!
list1=['donkey','balls'] list2=['donkey','scrotom'] set1=set(list1) set2=set(list2) print set1
set(['donkey', 'balls'])
print set2
set(['donkey', 'scrotom'])
symdiff = set1 ^ set2 symdiff
set(['balls', 'scrotom'])
