If the third option of the menu, i.e., Start marking, is selected, the program should allow the user to type in a file name for reading a series of student responses. You should only proceed to the marking task if the program has read both the solution and the class list.

Here's a sample running of this section without both the solution and the class list: --------------------------------------------------- Enter your choice: 3 --------------------------------------------------- Not Enough Information! -------------------------------------------------- ... 6.

Complete the read_data() function which returns a dictionary. The key of the dictionary item is the ID of a student and the value is a list of student responses from the corresponding student.

You may use the String data type's split() method to split apart the data from the file. You may need to use this method a few times along with a loop or two. For example, your file is organized so that one student's record occupies an entire line in the file. Splitting first on the line break will isolate each student's data. Then you will need to further split each item based on the separator character : to pull out the id and all responses. Next, you will need to split all responses into a list. For example: a student record is given as below:

N00000001:D,D,A,A,C,D,B,B,C,B,D,A,C,C,A

The function should convert the above record into a dictionary item in the following format:

Key: N00000001 Value: ['D', 'D', 'A', 'A', 'C', 'D', 'B', 'B', 'C', 'B', 'D', 'A', 'C', 'C', 'A']
