Python Program to Calculate Grade of a Student

This is a Python Program to take in the marks of 5 subjects and display the grade.

The program takes in the marks of 5 subjects and displays the grade.

1. Take in the marks of 5 subjects from the user and store it in different variables.
2. Find the average of the marks.
3. Use an else condition to decide the grade based on the average of the marks.
4. Exit.

Here is source code of the Python Program to take in the marks of 5 subjects and display the grade. The program output is also shown below.

 
sub1=int(input("Enter marks of the first subject: "))
sub2=int(input("Enter marks of the second subject: "))
sub3=int(input("Enter marks of the third subject: "))
sub4=int(input("Enter marks of the fourth subject: "))
sub5=int(input("Enter marks of the fifth subject: "))
avg=(sub1+sub2+sub3+sub4+sub4)/5
if(avg>=90):
    print("Grade: A")
elif(avg>=80&avg<90):
    print("Grade: B")
elif(avg>=70&avg<80):
    print("Grade: C")
elif(avg>=60&avg<70):
    print("Grade: D")
else:
    print("Grade: F")

1. User must enter 5 different values and store it in separate variables.
2. Then sum up all the five marks and divide by 5 to find the average of the marks.
3. If the average is greater than 90, “Grade: A” is printed.
4. If the average is in between 80 and 90, “Grade: B” is printed.
5. If the average is in between 70 and 80, “Grade: C” is printed.
6. If the average is in between 60 and 70, “Grade: D” is printed.
7. If the average is anything below 60, “Grade: F” is printed.

 
Case 1:
Enter marks of the first subject: 85
Enter marks of the second subject: 95
Enter marks of the third subject: 99
Enter marks of the fourth subject: 93
Enter marks of the fifth subject: 100
Grade: A
 
Case 2:
Enter marks of the first subject: 81
Enter marks of the second subject: 72
Enter marks of the third subject: 94
Enter marks of the fourth subject: 85
Enter marks of the fifth subject: 80
Grade: B
