title: Calculating and displaying infomation sliced from a text file
body: <p>I would like to ask for help on what is the best way to calculate and display information sliced from a text file.  The information in the text file looks like this:  John, 90, 87, 98    It contains a name and 3 test scores.  I have to display the information on a line for each person including the average of the grades.  I have been at this for days with very little progress.  I have tried loading the information into a list.  However, I haven't been able to convert the grades into integers.  What would be the best method to accomplish the desired results?  Also, how would I convert the grades to integers so I can calculate the average.</p>
