- Average Grade
- 90-100 A
- 80-89 B
- 70-79 C
- 60-69 D
- 0-59 F
# Grade calculator
print("Enter the marks you recieved in three subjects")
max = int(input("maximum marks in Every Subject"))
mks1 = int(input("Enter marks in Subject 1 "))
mks2 = int(input("Enter marks in Subject 2 "))
mks3 = int(input("Enter marks in Subject 3 "))
total = ((mks1+mks2+mks3))
ptg = total*100/(3*max)
print("Your percentage ",ptg)
if 90 < ptg <= 100:
print("Grade is A")
elif 80 < ptg <= 89:
print("Grade is B")
elif 70 < ptg <= 79 :
print("Grade is C")
elif 60 < ptg <= 69:
print("Grade is D")
elif 0 < ptg <= 59:
print("Grade is F")
