1.Given the argument passed to the function is a list containing integer values, what does the function return def mystery1(someListOfValues: list):total = 0for value in someListOfValues:total += valuereturn total/len(someListOfValues) 2. The function below is to find the largest value in a list passed by parameter. Does it work as intened (yes or no)? If not give an example of an argument it would not work for. def maxValue(someListOfValues:list):"""returns the largest value the list passed by parameter"""value = 0for num in someListOfValues:if num > value:value = numreturn value 3.Write a function called loadNames() that will open a file called names.txt and build a list of its contents and return it. Function Call: names = loadNames()print(names) Sample ouput: ['Nolan Rafaj\n', 'Brandon Brzuszkiewicz\n', 'Amanda Vozari\n', 'Chase Harper\n', 'Bryce Conner']
rite a function numPairs that accepts two arguments, a target number and a list of numbers. The function then returns the count of pairs of numbers from the list that sum to the target number. In the first example the answer is 2 because the pairs (0,3) and (1,2) both sum to 3. The pair can be two of the same number, e.g. (2,2) but only if the two 2’s are separate twos in the list.In the last example below, there are three 2’s, so there are three different pairs (2,2) so there are 5 pairs total that sum to 4. Sample usage: >> numPairs( 3, [0,1,2,3] )2

Given the following function header: def second_largest(1st: list[int]) -> int: Given a list of integers, return the second largest item in the list without modifying . Precondition: len(1st) >= 2 and given the following list of test cases (labelled TEST 1 through TEST 6): TEST 1: second_largest ([1, 2]) TEST 2: second_largest([e, 3]) TEST 3: second_largest([2, 1])| TEST 4: second_largest ([1, 3, 0]) TEST 5: second_largest([1, 3, 2]) TEST 6: second_largest([3, 1, 0])] Identify any tests which duplicate cases tested earlier in the list. For example, if TEST 3 duplicates something TEST 1 or TEST 2 have done, then select TEST 3 (as it has a duplicate test case). O TEST 1 O TEST 2 O TEST 3 O TEST 4 O TEST 5 O TEST 6
