Write a program that repeatedly asks the user to enter integer numbers corresponding to grades, or a blank line to exit. After the user enters a blank line, the grades they entered will be displayed as a list, in the same order they were entered. Then the program calculates and displays the minimum, maximum and average grades. Notes: - The user may choose to enter no grades. In that case, an empty list is displayed and the minimum, maximum and average are not displayed. - Printing a list will produce the output in the correct format (e.g., [1,2,3,4]). - You can use the built-in functions len() and sum() to calculate the average grade, and min() and max() to calculate the minimum and maximum grades. - The average should be be rounded to 1 decimal place. - The output must be in the format shown in the examples below, including the format of the prompt, and all spaces and punctuation.
