Scores Class Write a class named Scores which should have the following attribute: • _scores (a list to hold test scores, 0 - 100. Initially empty.) The Scores class should have an_init__method that creates the scores attribute. It should also have the following methods: • add_score: this method adds a score to the __scores list. It accepts a single score as it's' only argument. • get_average: this method accepts no arguments. If scores is empty, this method returns -1. Otherwise, it returns the average of all scores inscores. • get_high_score: this method accepts no arguments. if_scores is empty, this method returns -1. Otherwise, it returns the highest score in _scores. • get_low_score: this method accepts no arguments. ifscores is empty, this method returns -1. Otherwise, it returns the lowest score in scores. • -str_ This method returns a string similar to the following (assuming the scores contains 89, 77, 93): < 89 77 93 > Once you have written the class, write a program that creates an object of the class and prompts the user to enter a series of test scores. This data should be stored as the object's attribute. Use the object's accessor methods to retrieve the high score, low score, average, and stored scores and display this data on the screen. None of the methods interact with the user in any way. Format the average to 2 decimal places of precision.
