Your classmate wrote a simple function with two optional arguments: X which defaults to the string “a” and Y, which defaults to the empty list. It concatenates its first argument to itself and then appends that to the end of its second argument. Finally, it prints both arguments. 1 def foo(X = "a", Y = []): X = X + X Y.append(X) print X, Y When she called foo() with no arguments repeatedly, she was surprised and puzzled by the results: 2 به بیا . 3 4 >>> for i in range (4): foo() aa ['aa'] aa ['aa', 'aa'] aa ['aa', 'aa', 'aa'] aa ['aa', 'aa', 'aa', 'aa'] Explain to your classmate what is going on in this Python example and if the results are expected.

- Write a function that takes two arguments, a list L1 and a list L2. • If the length of the list L1 is greater than twice the length of the list L2, then append the first three values of L1 to the three last values of L2. E.g. if L1 = ‘(1 2 3 4 5 6 7) and L2 = ‘(8 9 10), then return ‘(1 2 3 8 9 10) Should be written in the Racket programming languageWrite a function named mostCharacters that takes a list of strings as an argument and a character as an argument. It then returns the string within the list that contains the highest count of the character. (If there is a tie for the highest count, return a list of all the strings) (IN PYTHON) For example, if you run mostCharacters(["cherry", "tomato", "salad", "shrimp"], 'r') it will return "cherry" If you run mostCharacters(["cherry", "tomato", "salad", "shrimp"], 's') it will return ["salad", "shrimp"] (IN PYTHON)IN RACKET PLEASE Write a function that takes two lists as input, a list L1 containing characters and a list L2 containing numbers. For each of the number n contained in L2, the function will display the first n character of the list L1. For example: L1 '("h" "e" "l" "l" "o" "w" "o" "r" "l" "d") L2 '(2 3 1 5 10) Output: he hel h he l l o h e l l o w o r l d.
- In Python: Write a function that takes in two lists (A and B) as parameters, and an integer (sum). Both lists have the same size. The function returns True if there are two numbers: a in A, and b in B, where a + b = sum. The function must run in O(nlogn), where n is the size of any of the two listsWrite a function that accepts a number and a string as arguments. It should return a list having n elements such that the i th element of the list has the string repeated i times. For example, if the arguments are 3 and 'Hello' then the function should return ['Hello', 'HelloHello', 'HelloHelloHello']. Use list comprehension to generate this list.Write a function named mostCharacters that takes a list of strings as an argument and a character as an argument. It then returns the string within the list that contains the highest count of the character. (If there is a tie for the highest count, return a list of all the strings) For example, if you run mostCharacters(["cherry", "tomato", "salad", "shrimp"], 'r') it will return "cherry" If you run mostCharacters(["cherry", "tomato", "salad", "shrimp"], 's') it will return ["salad", "shrimp"]
- Write a function that takes two lists as input, a list L1 containing characters and a list L2 containing numbers. For each of the number n contained in L2, the function will display the first n character of the list L1. For example: L1 '("h" "e" "l" "l" "o" "w" "o" "r" "l" "d") L2 '(2 3 1 5 10) Output: he hel h he l l o h e l l o w o r l d.how to write a function in python 3 that take a tuple t = (7,8,4,20,11) and returns a list which includes all the numbers which are not a prime number.Given both a list x and a tuple y, write a function called sum_list_andOr_tuple that sums all the elements of both data structures and returns the sum. There is also an optional boolean argument into the function called separate which, if True, causes the function to return the sum of the list and the tuple separately (returns two values); separate is False by default. Please note that the function DOES NOT print anything - it only returns a value(s). See the sample output below: >>> my_list = [0, 9, 99]>>> my_tuple = (8, 12)>>> result = sum_list_andOr_tuple(my_list, my_tuple)>>> print(result) Output: 128>>> result = sum_list_andOr_tuple(my_list, my_tuple, separate = True)>>> print(result) Output: 108, 20
- Please answer it in Python Write a function indice_de that takes as an argument an integer (supposedly even) and a list, and returns the index to which this integer appears in the list. If the integer does not appear, the function will return None. It is assumed here for simplicity that the integer searched for does not appear several times in the list. Hint: if the for e in list loop doesn't suit you, remember that you can make a for + range or a while. .. Example: indice_de(12, [4, 7, 12, 0, 21, 5]) return => 2 (because 12 is placed at index 2), and indice_de(6, [4, 7, 12, 0, 21, 5]) return => None. Write a function trouve_premier_pair that takes a list as an argument and returns the even integer that appears first in the list. If the list does not contain an even integer, the function will return None. Example: trouve_premier_pair([1, 15, 4, 7, 12, 3]) return =>4 and trouve_premier_pair([1, 17, 7]) return =>None. Write a function extrait_even that takes as an…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']PYTHON!!!! Complete the below function which takes a list of distinct positive integers and a target positive integer value, and then returns a list of the pairs of integers where each pair sums up to the target value. Each pair is represented as a tuple. For example, pairsum([3,2,6,1,5,4], 7) should return [(1,6), (2,5), (3,4)] If there are no pairs matching the target value, then you should return an empty list. IMPORTANT: the first integer in a tuple must be always smaller than the second integer. So, (5,3) is wrong and (3,5) is correct, and the resulting list must be in ascending order of first element in each tuple. """ def pairsum(list1, target):
