It doesn't matter just use the language convention, in python it's spaces in c it might be tabs. It really doesn't matter. My only pet peeve with spaces is people will occasionally use a number that is not a multiple of the indentation to align things with the text in the previous line. I find it unpleasant(harder) to read such code.
