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 …

check your code

I`ve copied it to to a new file and result is the same - no "error" message

i added an if statement, if score > 1.0, print('error')

You need to define the range of acceptable scores before before specifying the grades.
Here is my code that works well for values below 0 and above 1.

Receive input from user and convert to float

inp = input("Enter Score: ")
score = float (inp)

Define boundary of scores

if score > 1:
print ('Only numbers less than 1 and bigger than O are allowed')
elif score < 0:
print ('student cannot have a negative score')

Give suitable results

elif score >= 0.9:
print ('A')
elif score >= 0.8:
print ('B')
elif score >= 0.7:
print ('C')
elif score >= 0.6:
print ('D')
elif score < 0.6:
print ('F')

Hope it helps!
