The situation and solution given above is pretty simple. The issue of updating specific values in a list of objects (often referred to as an array, but that's a discussion for a different time) has more practical and industrial application. The problem you tend to run into is thinking that looking at a value in a specific cell, e.g. my_array[0][0] returns 'some value' will also let you change that value through an assignment e.g. my_array[0][0] = 'new value'. You will find that depending on how you defined your array, the change shows in the same row across the columns, not what you are needing. Look at the example code as an illustration of creating, and managing a multidimensional list of objects (array).
