Или:

grade = float(input())

def solve():
    if 2 <= grade <= 6:
        return {2.00 <= grade <= 2.99: "Fail",
                3.00 <= grade <= 3.49: "Poor",
                3.50 <= grade <= 4.49: "Good",
                4.50 <= grade <= 5.49: "Very Good",
                5.50 <= grade <= 6.00: "Excellent"}[True]

print(solve())
