Can anyone give me these solution PLZ.

a) Write a new function (called inputMarks) which will read the file marks.txt and place individual students records into a list (effectively a ‘list of lists’). The function should take the marks list as a parameter.
You may not assume that you know how many records are in the input file – it must work for any number of lines.
For each line in the input file you should create an individual list with four elements (listed above). Use the ‘split’ function to help you with this. Once you have created this list, add it to the marksList. The result of executing inputMarks should be a list of student records – one for each line in the file.
b) Write a function called calcGrade. This function takes a mark (type ‘int) and returns a grade. The grades are calculated as follows.
16 – 20 HD
14 – 15 D
12 – 13 C
10 – 11 P
< 10 F
c) Write a function called ‘printIndividualRecord’. It should take a list (corresponding to a single student record) as a parameter. If the record is
12331 Bruce Willis 19
the function should print out the details of the record in the following format
‘Willis, Bruce: Student number 12331 scored 19 / 20 – HD awarded’
d) Write a function called ‘printAllRecords’, which calls printIndividualRecord for each record in marksList. It should take marksList as a parameter.
Examine the functions already authored in assignment2.py.
In the code, write a high-level description of what each of these functions is intended to do as a comment above the function code. This description should be no longer than five lines. Marks will be awarded according to how well your response reflects your understanding.
Examine the function ‘sortListUsingSelectionSort’ that has been written in assignment2.py. This function is not complete. Use the functions from taskB to complete the implementation of this function. Note – it should not be necessary to move (change the order of) or delete the code that is already there.
When complete the function should have sorted the list in descending order (biggest item first).
