 ## Code Sample
 
-    nums = [1,2,3,4]
-    print(*nums) # prints 1 2 3 4
+    # Example 1 : zipping 2 lists.
     numsAndNames = zip([1,2,3],['one','two','three'])
     print(*numsAndNames) # prints (1,'one') (2,'two') (3,'three')
+    
+    # Example 2 : zipping a list of lists.
+    list_of_lists = [[1,2,3,4,5],[6,7,8,9,0],[10,11,12,13,14,15]]
+    lists_zip = zip(*list_of_lists)
+    print(*lists_zip) # prints (1,6,10) (2,7,11) (3,8,12) (4,9,13) (5,0,14)
+                      # Notice how the 15 from the last list is truncated.
