(In python) Assume that L1 and L2 are two non-empty lists. Write function that takes as input these two lists and returns a list of all elements from both lists (without duplicates). Note, those duplicates could reside in the same list. For example, if L1 = [1,2,3,2,1] and L2 = [3,3,1,5,4], then the program should return [1,2,3,4,5], not necessarily in that order. b) Write a one-line list comprehension that takes the alphabetic string Str (i.e. that only has alphabetic characters in it) and returns a list of each non-vowel character of the given string duplicated four times. For example, if Str = "popular", then the list comprehension would be [pppp, pppp, llll, rrrr].
