Question

Define a function named "excludeItem" 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

Answer 1

def excludeitem(item1, item2):
    new_item = []
    max = item1 if len(item1) > len(item2) else item2
    min = item1 if len(item1) < len(item2) else item2
    for i in max:
        if i in min and i not in new_item:
            new_item.append(i)
    return new_item

print(excludeitem([1, 2, 2, 3], [7, 2, 5, 3, 3]))
