Hints

Check the highest grade first.

Because elif stops at the first match, you only need >= checks.

Solution explanation

Checking from the top grade down means each elif only needs a single >= test.

Show solution

m = int(input())
if m >= 90:
    print("A")
elif m >= 75:
    print("B")
elif m >= 50:
    print("C")
elif m >= 35:
    print("D")
else:
    print("F")
