Suppose we use a dictionary to maintain gradebooks for several IS courses: IS_gradebooks {'ISOM2020': [59, 100, 80, 55, 95, 87, 95, 98, 74, 69, 92, 94, 75, 97, 43, 57], 'ISOM3400': [98, 73, 45, 88, 72, 94, 82, 100, 89, 52], 'ISOM3600': [24, 44, 100, 81, 91, 93, 87, 72, 55], 'ISOM4200': [90, 56, 78, 67, 90, 93]} Write a dictionary comprehension to count how many students earned scores below 60 for each course. The expected output should look like the following: ISOM3600': 3, ISOM4200': 1} = {'ISOM2020': 4, 'ISOM3400: 2,
