You need to return a tuple that contains the average of attendance, average of exams, and average of homeworks for the whole class.

EXERCISES Exercise 1 Write a function "finalGrade" that takes a list "classList" which contains a sublist for each student. Each sublist contains three grades; attendance, exam grade, and homework grade. You need to return a tuple that contains the average of attendance, average of exams, and average of homeworks for the whole class. Sample Input classList = [[20,80,90],[10,60,40],[17, 77,56], [21,99,99]] Sample Output (17,79,71.25) *Hints: The class has 4 students average attendance = (20+10+17+21)/4 = 17 average exams = (80+60+77+99)/4 = 79 average homeworks = (90+40+56+99)/4 = 71.25
8-9. Messages: Make a list containing a series of short text messages. Pass the list to a function called show_messages(), which prints each text message. 8-10. Sending Messages: Start with a copy of your program from 8-9. Write a function called send_messages() that prints each text message and moves each message to a new list called sent_messages as it’s printed. After calling the function, print both of your lists to make sure the messages were moved correctly. 8-11. Archived Messages: Start with your work from 8-10. Call the function send_messages() with a copy of the list of messages. After calling the function, print both of your lists to show that the original list has retained its messages. 8-12. Sandwiches: Write a function that accepts several items a person wants on a sandwich. The function should have one parameter that collects as many items as the function call provides, and it should print a summary of the sandwich that’s being ordered. Call the function three times,…
17. The following function takes a parameter that is a list of integers; the list has at least one element. It is supposed to find the integer that is the largest and find the position of that integer in the list. The function has two incorrect lines of code that make the function compute the results incorrectly. Several lines are highlighted (bold, underlined) which COULD be incorrect. In the following questions, choose the correct line of code that should be in the function. 1 def findlarge(intlist): 2 largest = 0 3 pos = 0 for i in range(1,len(intlist)): if largest > intlist[i: 4 5 largest = intlist[i] pos = i return (largest, pos) 8 Select one of the following to correct a line of code in the function. a. Line 2 should be: largest = -1 b. Line 2 should be: largest = intlist[0] c. Line 4 should be: for i in range(0,len(intlist): %3D d. Line 4 should be: for i in range(1,len(intlist)-1): e. Line 8 should be: return largest 18. Select one of the following to correct a line of code in…
Function 1: draw_subregion Complete the implementation of draw_subregion. This function has the following parameters: my_turtle: A turtle object (which will do the drawing) polygon_points: A list of (x, y) points (i.e. a list of tuples) that defines the points of a polygon. This function should make the turtle draw the polygon given by the points. Make sure that you lift your pen before heading to the first point. You should also make sure you return to the very first point at the end (i.e. you will go to the first point in the list two times: once at the beginning, and once at the end). Language Python
The mapped list pattern Our second pattern is the mapped list pattern, described in video 4 3 mapped list pattern. Often we need to write a function that takes a list as a parameter and returns a new list in which each item in the original list is "mapped" to a new item in the result list. For example, the following function takes a list of numbers as a parameter and returns a list of all the numbers squared, e.g. squares ( [1, 3, 7]) returns [1, 9, 49]. def squares (nums): "Returns the squares of the given numbers""" result = [] for num in nums: result.append (num * num) return result Although this is just a special case of the accumulator pattern, it is so common that we give it its own name: the mapped list pattern. Consider the following function: def squares(nums): ""Returns the squares of the given numbers""" result = [] for num in nums: result.append (num * num) return result If the main program calls print(squares ( [5, -3, 2, 7]) what is the state table for the function…
Problem DNA: Subsequence markingA common task in dealing with DNA sequences is searching for particular substrings within longer DNA sequences. Write a function mark_dna that takes as parameters a DNA sequence to search, and a shorter target sequence to find within the longer sequence. Have this function return a new altered sequence that is the original sequence with all non-overlapping occurrences of the target surrounded with the characters >> and <<. Hints: ● String slicing is useful for looking at multiple characters at once. ● Remember that you cannot modify the original string directly, you’ll need to build a copy. Start with an empty string and concatenate onto it as you loop. Constraints: ● Don't use the built-in replace string method. All other string methods are permitted. >>> mark_dna('atgcgctagcatg', 'gcg') 'at>>gcg<<ctagcatg' >>> mark_dna('atgcgctagcatg', 'gc')…
A lecturer makes use of a list to store the scores of a test similar to the following: var scores = [45,50,89,90,46,67] Each element in the list represents the score obtained by student i, where i is the respective index. To help the lecturer perform some operations, you are required to write and test the following functions Function called captureScores This function accepts an integer representing the number of students in the class e.g. 5 It then captures the scores for the 5 students, one by one, adding them to a list of integers Finally, it returns the list once all n scores have been captured. Hint – Make use of a loop. Start with an empty list, use the add() method to populate your list with scores, one by one as they are captured.
***python only*** Write a function votes_by_race() which takes a list of dicts as a parameter and returns a dict. For example, given the following list: votes = [{'for': 'A, 'age': 35, 'race': 'w'}, {'for': 'B', 'age': 40, 'race': 'b'}, {'for': 'B', 'age': 20, 'race': 'b'}, {'for': 'A', 'age': 30, 'race': 'a'}, {'for': 'A', 'age': 41, 'race': 'w'}, ] The call votes_by_race(votes) should return the following dict:{"White": 2, 'Black': 2, 'Asian': 1, "Hispanic': 0}

Problem 1: Lo Shu Magic Square The Lo Shu Magic Square is a grid with 3 rows and 3 columns. The Lo Shu Magic Square has the following properties: • The grid contains the numbers 1 through 9 exactly.• The sum of each row, each column, and each diagonal all add up to the same number. This is shown in Figure ➔➔➔ "Attached Image" In a python program, you can simulate a magic square using a two-dimensionallist. Write a function that accepts a two-dimensional list as an argumentand determines whether the list is a Lo Shu Magic Square. Test thefunction in a program. Below is the main() function and some globalconstants. You may need to define multiple functions to organize yourcode. # Global constants ROWS = 3 # The number of rowsCOLS = 3 # The number of columnsMIN = 1 # The value of the smallest numberMAX = 9 # The value of the largest numberdef main():# Create a two-dimensional list.test_list = [ [4, 9, 2],[3, 5, 7],[8, 1, 6] ] # Display the list in row and column…
palindromes Write a function palindromes that accepts a sentence as an argument. The function then returns a list of all words in the sentence that are palindromes, that is they are the same forwards and backwards. Guidelines: • punctuation characters .,;!? should be ignored • the palindrome check should not depend on case Sample usage: >>> palindromes ("Hey Anna, would you prefer to ride in a kayak or a racecar?") ['Anna', 'a', 'kayak', 'a', 'racecar'] >>> palindromes ("Able was I ere I saw Elba.") ['I', 'ere', 'I'] >>> palindromes ("Otto, go see Tacocat at the Civic Center, their guitar solos are Wow!") ['Otto', 'Tacocat', 'Civic', 'solos', 'wow'] >>> palindromes ("Otto, go see Tacocat at the Civic Center, their guitar solos are wow!")==['Otto', 'Tacocat', 'Civic', 'solos', 'wow'] True
