Question

Write a Python program that creates a class which represents a Student Grade. The class includes a function that reads a text file called Course_Score.txt. A sample of the file is provided below. Each row in the file corresponds to the Last Name, First Name, ClassWork score (100), Mid-Term score (100), and Final-Exam score (100). Also include the the following functions to process the content read from the file. a. getData(): This method reads the data from a file and stores the data as a list. b. grade(): This method calculates total score, percentage and grade for each student. A grade (above 90%), B grade (above 80%), C grade (above 60%), D grade (above 50%), and F grade (below 50%) c. highestTotal() and lowestTotal(): These methods calculate highest and lowest total scores in class.

Sample input file: Course_Score.txt

SOLUTION-
I have solve the problem in python code with comments and screenshot for easy understanding :)

CODE-

main.py

#python code
#class
class studentGrades:
    # to read the file
    def __init__(self):
        self.file=open('Course_Score.txt','r')
        self.data=[]
        self.grades=[]
        self.totals=[]
    #gets data from file   
    def getData(self):
        for line in self.file.readlines():
            self.data.append(line.rstrip().split())
        self.file.close()
        return (self.data)
          
    def grade(self):
        #loop to gives the grades to students
        for d in self.data:
            self.Fname,self.Lname,*self.scores = d
            self.totalScore = int(self.scores[0])+\
            int(self.scores[1])+int(self.scores[2])
            self.totals.append(self.totalScore)
            self.percent = round(self.totalScore/3)
            if self.percent>=90:
                self.grade='A'
            elif self.percent>=80:
                self.grade='B'
            elif self.percent>=60:
                self.grade='C'
            elif self.percent>=50:
                self.grade='D'
            elif self.percent<=50:
                self.grade='F'
            self.grades.append((self.Fname+' '+self.Lname,self.totalScore,self.percent,self.grade))
            #prints the name , total , nPercentage ,grades
            print('Name: {0}\nTotal Score: {1}\nPercentage: {2}\nGrade: {3}\n'\
            .format(self.Fname+' '+self.Lname,self.totalScore,self.percent,self.grade))
    #for highest
    def highestTotal(self):
        return max(self.totals)
    #for lowest
    def lowestTotal(self):
        return min(self.totals)
#initalize
Grades = studentGrades()
data = Grades.getData()
#print data
print(data)
print()
#call functions
Grades.grade()
highTotal = Grades.highestTotal()
lowTotal = Grades.lowestTotal()
#print high and low
print('The highest total score is {}'.format(highTotal))
print('The lowest total score is {}'.format(lowTotal))
