Using Python. Write a function clean2(aList) that takes a list of integers aList as argument, and modifies this list, such as multiple occurrences of values have been removed. The procedure does not return a list: it modifies its argument (reference aList). 3 For instance, the following statements: al = [1,2,3,4,4,4,5,1,2,1,5] print(al) clean2(al) print(al) print the following result (a different order of values is acceptable): [1,2,3,4,4,4,5,1,2,1,5] [1,2,3,4,5]

Answer #1 
def clean2(aList):
    i = 0
    while(i<len(aList)):
        if aList.count(aList[i]) > 1:
            aList.remove(aList[i])
        else:
            i += 1

al = [1,2,3,4,4,4,5,1,2,1,5]
print(al)
clean2(al)
print(al)

    Python Write a function named minGap that takes in a list of integers and returns the minimum ‘gap’ between values in the list. The gap between two adjacent values in a list is defined as the second value minus the first value. For example, suppose we have the following list: [1, 3, 6, 7, 12] The first gap is between indices 0 and 1 and its value is 3 − 1 = 2. The second gap is 6 − 3...

    For Python [25 pts] Write the method divisorList(aList, divisor) that takes in a list with elements of any data type and a divisor which is in the form of an integer. The output is a sorted list of only the integers that are divisible by the divisor. Example: divisorList([1, 1, 12, 'a', 90, 34], 2) will return [12, 34, 90] since 12, 90, and 34 are all divisible by two. Note that the returned list is sorted from smallest to...
