For example: grades ['A, F, C, 'F, A, 'B', A, 'C, 'A, 'B'] Write a Python expression that creates a list named frequency, in which the elements are the number of times each of the letters A, B, C, D and F appear in grades. For example, for the above value of grades, the following would be correct output: frequency [4, 2, 2, 0, 21 Your expression must give the correct values for any list of grades, not just the one in your list. (Test your code with multiple test cases!) Hint: use the list method count. 2. This question practices list membership, list indexes and list slices a. Write a Python statement that creates a list named dog_breeds that contains the elements b. Write a Python statement that uses list slicing to create a list herding dogs that is made up c.
