Intention of my program is to group all the comments based on the author name. I would like to show all the comments from one author together. I am trying to perform this in Python. is there a way to simply collect the list of a person’s comment based on name property?

It simply implies they have to first register and then comment. How to do this in cool way and with out attracting much headache in the future? Great thanks for your kind help.
