[pygame] Storing images in a list

[Chris <c4@xxxxxxxxxxxxxxxxxxxxxx>]

I'm doing a board game on an 8 by 8 grid.

I have two colors of units--red and blue.

My question is this:

When an element of the list says <Surface 50x50x32>, is that pointing to 
a spot in the memory or is the actual image being stored in that index? 
 Would I have 64 images in my list if every space is occupied or would 
I have just 2 images in memory?

So I guess that's two questions. :p

Thanks.
