school has following rules for grading system:
a. Below 25 - F
b. 25 to 45 - E
c. 45 to 50 - D
d. 50 to 60 - C
e. 60 to 80 - B
f. Above 80 - A
Ask user to enter marks and print the corresponding grade.
Answer
print ("Enter marks")
marks = int(input())
if marks<25: print ("F")
elif marks>=25 and marks<45: print ("E")
elif marks>=45 and marks<50: print ("D")
elif marks>=50 and marks<60: print ("C")
elif marks>=60 and marks<80: print ("B")
else: print ("A")
