# 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.


#collect input from user
score = input ("Enter Score between 0.0 and 1.0 to see grade: ")

#use try except to catch invalid inputs like alhpabets
try :

    fscore = float (score)
    if fscore >= 0.9:
        print ("A")
