# Python code to find student grade 

class Student:
    def __init__(self):
        self.__roll=0
        self.__name=""
        self.__marks=[]
        self.__total=0
        self.__per=0
        self.__grade=""
        self.__result=""

    def setStudent(self):
        self.__roll=int(input("Enter Roll: "))
        self.__name=input("Enter Name: ")
        print("Enter marks of 5 subjects: ")
        for i in range(5):
            self.__marks.append(int(input("Subject "+str(i+1)+": ")))
			
    def calculateTotal(self):
        for x in self.__marks:
            self.__total+=x
			
    def calculatePercentage(self):
        self.__per=self.__total/5
		
    def calculateGrade(self):
        if self.__per>=85:

        elif self.__per>=55:

        else:
            self.__grade="F"
			
    def calculateResult(self):
        count=0
        for x in self.__marks:
            if x>=50:
                count+=1
        if count==5:
            self.__result="PASS"
        elif count>=3:
            self.__result="COMP."
        else:
            self.__result="FAIL"
			
    def showStudent(self):
        self.calculateTotal()
        self.calculatePercentage()
        self.calculateGrade()
        self.calculateResult()
        print(self.__roll,"\t\t",self.__name,"\t\t",self.__total,"\t\t",self.__per,"\t\t",self.__grade,"\t\t",self.__result)


def main():
    #Student object
    s=Student()
    s.setStudent()
    s.showStudent()

if __name__=="__main__":
