+#Sets are lists with no duplicate entries. Let's say you want to collect a list of words used in a paragraph:
+print(set("my name is Eric and Eric is my name".split()))
+
+
+# Sets are a powerful tool in Python since they have the ability to calculate differences and intersections between other sets. For example, say you have a list of participants in events A and B:
+#To find out which members attended both events, you may use the "intersection" method:
+
+a = set(["Jake", "John", "Eric"])
+print(a)
+b = set(["John", "Jill"])
+print(b)
+
+print(a.intersection(b))
+
+#To find out which members attended only one of the events, use the "symmetric_difference" method:
+print(a.symmetric_difference(b))
+
+#To find out which members attended only one event and not the other, use the "difference" method:
+print(a.difference(b))
+
+#To receive a list of all participants, use the "union" method:
+print(a.union(b))
