Question

This is an assignment for python.

Download the code “

GradeBook.py

”

You will be modifying the code to do the following:

1)

create an empty dictionary named “FinalAverages”

2) In one for loop you will zip all lists together and get their individual members on each iteration. You can name

these what ever you want.

3) on each iteration: Calculate the WEIGHTED average using the weights provided, and then add a new dictionary

value to the dictionary “

FinalAverages

”. The KEY for this dictionary will be the name on this iteration, and the

VALUE will be the average of the student.

4)

Print

the whole

dictionary,

and

then

print

ONLY ”Jack”

5) BONUS: if you create a function that takes an input of the 4 lists, and an output of the appropriate dictionary:

adding 1 point. Your code must then use this function to create the appropriate dictionary, apply the weights

(Store them in that function), and then output the

values you got.

Gradebook.py is:

Students = ['Bill', 'Sue', 'Janet', 'Cindy', 'Ray', 'Jack', 'Barbra', 'Matt', 'Joey', 'Adam', 'Becky', 'Mona']
Exam1 = [100, 80, 26, 45, 89, 65, 92, 75, 76, 15, 80, 50]
Exam2 = [88, 95, 55, 60, 81, 25, 70, 100, 95, 70, 72, 10]
Exam3 = [65, 92, 100, 80, 26, 92, 55, 60, 80, 55, 60, 75]
scaleExamOne = 0.3
scaleExamTwo = 0.3
scaleExamThree = 0.4

Answer 1

Python code:
def waverage(students,exam1,exam2,exam3,scaleExamOne,scaleExamTwo,scaleExamThree):
result = {}
for i in range(len(students)):
wavg = (exam1[i]*0.3) + (exam2[i]*0.3) + (exam3[i]*0.4)
result[students[i]] = wavg
print(result)
print("Jack Details:")
print(result['Jack'])
  
Students = ['Bill', 'Sue', 'Janet', 'Cindy', 'Ray', 'Jack', 'Barbra', 'Matt', 'Joey', 'Adam', 'Becky', 'Mona']
Exam1 = [100, 80, 26, 45, 89, 65, 92, 75, 76, 15, 80, 50]
Exam2 = [88, 95, 55, 60, 81, 25, 70, 100, 95, 70, 72, 10]
Exam3 = [65, 92, 100, 80, 26, 92, 55, 60, 80, 55, 60, 75]
scaleExamOne = 0.3
scaleExamTwo = 0.3
scaleExamThree = 0.4
waverage(Students,Exam1,Exam2,Exam3,scaleExamOne,scaleExamTwo,scaleExamThree)
