Exercise 3.3 - Python for Everybody

Exercise 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 message. 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

Enter score: 0.95
A

Enter score: perfect
Bad score

Enter score: 10.0
Bad score

Enter score: 0.75
C

Enter score: 0.5
F

Run the program repeatedly as shown above to test the various different values for
input.


score = input("Enter your grade: ") # asks user for their grade
try: 
    score = float(score)
    if (score) >= .90 and score <=1.0:
        print("A")
    elif score >= .80 and score <.9:
        print("B")
    elif score >= .70 and score <.8:
        print("C")
    elif score >= .60 and score <.70:
        print("D")
    elif score >= 0 and score < .60:
        print("F")
    else:
        print("Bad Score")
except:
    
    print("Bad Score")
