Define a function named "excludeltem" which take two parameters (item1 & item2) and both are list. This function will create a separate list named "result" which only include items found in both lists. The result list should not have duplicate value. For example, given item1 = [1,2,3,4,2,1] while item2 = [2, 4, 4, 2]. This function will return a result of [2,4]. Note that the output value is unique (no duplicate). The function must be able to accept other parameters as well i.e. list of strings or mixture of strings and digits
