Solution

#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.



#Solution:
score = input("Enter Score: ")
s=float(score)

if s >= 0.9 and s <=10:
    print("A")
elif s>= 0.8 and s<0.9:
    print("B")
elif s>= 0.7 and s<0.8:
    print("C")
elif s>= 0.6 and s<0.7:
    print("D")
elif s<0.6 and s>=0.0:
    print("F")
else:
    print("Out of range! Please re-run.")
