Question

I REALLY NEED HELP!!!!!

 

We learnt this week that lists can be multi-dimensional. For e.g., the following is another example of 2-D multidimensional list. Each row contains student name followed by their grades in 5 subjects:

students = [ ['Anna', 98.5, 77.5, 89, 93.5, 85.5], ['Bob', 77, 66.5, 54, 90, 85.5], ['Sam', 98, 97, 89.5, 92.5, 96.5] ]

To access, a specific row, you would use students[row_number][column_number].

  • students[0][0] would print 'Anna'
  • students[0][1] would print 98.5

Write a program that defines a function that takes a list as an argument, adds the scores of each student, calculate average for each student (append them to a separate list) and display them.

Your program should:

  1. Define a function display_average(students) that takes in a 2-D list as an argument. Display the original list using for/while loop. Calculate and display the average of each student.

  2. You do not need to ask user for input. You can use your own 2-D lists with at-least 2-rows.
