Entry level Python programming question:

3. (3 points) Write a program that ask the user to enter five valid test scores. The program should display a letter grade for each score and the average test score. Write the following functions in the program: get_valid_score This function should ask the user to enter a score. If the score is less than 0 or greater than 100, the function should ask user re-enter a score, until user enter a valid one. Finally the function returns the valid score. calc_average This function should accept a list of test scores as argument and return the average of the scores. determine-grade This function should accept a test score as an argument and return a letter grade for the score base on the grading scale in Table 2a. Input Output Input Score Output Grade Score Grade Score (90 100 [80 90) [70 80 (60 70) 10 60) Grade A B C D F 97 89B 75 C 91 A 82 B 27 F -10 101 100 Invalid Input. Invalid Input. (a) 0 average 72.80 F B D 82 65 (b) average 68.80 (c) Test your program with the data in Tables 2b and 2c. Finally, format your program to match the sample terminal. Your output should exactly match the sample output, character for character, including all white space and punctuation. User input in the sample has been highlighted in Pappy's Purple to distinguish it from the program's output, but your user input does not need to be colored. Save your program as test_avg-grade.py Terminal $ python test_avg_grade.py Enter a score: 97 The letter grade for 97.0 is A. Enter a score: -10 Invalid Input. Please try again. Enter a score: 101 Invalid Input. Please try again. Enter a score: 100 The letter grade for 100.0 is A. Enter a score: 0 The letter grade for 0.0 is F. Enter a score: 82 The letter grade for 82.0 is B. Enter a score: 65 The letter grade for 65.0 is D. The average test score is 68.80
