Write a function called find value that takes a list of lists and a value as arguments and returns a list giving the indices of the (sub)list and position in that list where the first instance of the value was found. If the value does not exist in any of the (sub)lists, the function returns [-1, -1]. For example, given: my_list = [[2, 5], [1, 3, 4], [4], [7, 3]] the call: find_value(my_list, 4) would return: [1, 2] and the call: find_value(my_list, 7) would return: [3, 0] and the call: find_value(my_list, 8) would return: [-1, -1] def find_value(lst, val): Problem - 6: Write a function sum_without_twenties(a, b, c) that returns the sum of three int arguments a, b, and c. However, do not include any int as part of the sum if it is within the range [20, 29] (inclusive). Problem -7: Write a function debug () that takes in two sets, and makes a new set that contains the elements both sets have in common. If "bug" is one of the elements, remove that from the new set. Return the new set. For example, debug ({"bug", "rice", "apple"}, {"rice", "bug", "sugar"}) should evaluate to {'rice'). Note: You may be asked to demonstrate the working code of any problem.
