Problem Statement

Python program to get student details as input and then print the result after updating the marks.

Problem Description

We need to get input from users for the roll number, name and marks of three subjects. Then we need to calculate the percentage and print result, and reprint it after giving extra marks.

Steps to get and put details of student:

• Step 1: Create a class named Student.
• Step 2: The method of the class, getStudentDetails() gets input from the user. printResult() calculates result and prints it.
• Step 3: We will also add extra marks (9), to a subject.
• Step 4: Then print the result.

Program to illustrate printing student result

class Student:
    def getStudentDetails(self):
        self.rollno=input("Enter Roll Number : ")
        self.name = input("Enter Name : ")
        self.physics =int(input("Enter Physics Marks : "))
        self.chemistry = int(input("Enter Chemistry Marks : "))
        self.maths = int(input("Enter Math Marks : "))

    def printResult(self):
        self.percentage = (int)( (self.physics + self.chemistry + self.maths) / 300 * 100 ); 
        print(self.rollno,self.name, self.percentage)

S1=Student()
S1.getStudentDetails()

print("Result : ")
S1.printResult()

S1.physics += 9

print("result after adding grace marks...")
S1.printResult()

Output

Enter Roll Number : 001
Enter Name : John
Enter Physics Marks : 87
Enter Chemistry Marks : 45
Enter Math Marks : 95
Result : 
001 John 75
result after adding grace marks...
001 John 78
