Write a Python program using a function called grades_() 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 < 0.7 F. If the user enters a value out of range, print a suitable error message and exit. For the test, enter scores of 0.85 and 2 to get the score of B and error message that you have print for the user, respectively.
