I’ve read various things about guids and how safe they are for not repeating the same value. I have a slight twist on the question though: Guids seem to always use hyphens to break them into chunks. If I dispose of these hyphens, does it hurt the uniqueness of the number in any way? If i recall, each block is always padded out to the same number of digits, so if that is true I would assume they should not suffer from removing the hyphens.
You are correct. Hyphens are just for formatting. If you look at http://docs.python.org/2/library/uuid.html you’ll notice all the different formats are really the same UID.
