Write a function, find lists_avg(...), that computes the average of a list of numbers. The function accept one parameter, list_of_lists, from which you should extract each list and compute the average of the values in each list. You can assume that the values in the list are either integers or floats. The function should return a list of averages of the lists. Ex. list-of-lists [[1,2,3], [2,4], [3,3,3]] print(find_lists_avg(list_of_lists)) should output: [2.0, 3.0, 3.0]
