Programming for Everybody (Getting Started with Python) || Assignment_3.3 || Week 5 | Graded External Tool

3.3 Write a program to prompt for a score between 0.0 and 1.0. If the score is out of range, print an error. If the score is between 0.0 and 1.0, print a grade using the following table:
Score Grade
>= 0.9 A
>= 0.8 B
>= 0.7 C
>= 0.6 D
< 0.6 F
If the user enters a value out of range, print a suitable error message and exit. For the test, enter a score of 0.85.

Code :

score = input("Enter Score: ")

s = float(score)

if 0.0 <= s <= 1.0:

    if s >= 0.9:

        result = "A"

        print("result")

    elif s>=0.8 :

        print("B")

    elif s>=0.7 :

        print("C")
