Question

Hello, I need help with this assignment.

Create a python program making use of lists and a dictionary.

Deliverables: Python File and a flowchart In first list, there will be four of your courses of your choice. In the second list there will be four grades corresponding to the four courses.

Define a dictionary that assigns grade points to each possible grade.

Calculate the GPA by adding each grade point (by reference to the dictionary) divided by the length of the second list. (use the len() statement for this. Here the list element will be embedded as the key in referencing the grade points. (e.g. [list2 [0] ]), this will yield the grade points of the first grade in the second list (list2).

Display each course with their grade, the total grade points and the GPA. Display the proper string literals that will identify your output. First assign the course list, then assign the grades list. Create the dictionary of grades with grade points. Calculate the total grade points. divide the grade points by the length of the grades list.

class Grade:

    self.hours = float(hours)
    self.qpoints = float(qpoints)

def getName(self):
    return self.name

    return self.hours

    return self.qpoints

def gpa(self):
    return self.qpoints/self.hours

def addGrade(self, OneGradePoint , credits):
    self.hours += credits
    self.qpoints += credits*OneGradePoint

def addLetterGrade(self, grade):
    total = 0
    for i in grade(A,B,C,D,E,F):
        if grade == 'A':
                     total = total + 4.0
        elif grade == 'A-':
                     total = total + 3.7
        elif grade == 'B+':
                     total = total + 3.3

                     total = total + 1.7
        elif grade == 'D+':
                     total = total + 1.3
        elif grade == 'D':
                     total = total + 1.0
        elif grade == 'E':
                     total = total + 0.0
        elif grade == 'F':
                     total = total + 0.0

# after user has entered all grades, compute the cumulative GPA
    if Grades.getHours() == 0.0:
