I want to print a series of list elements some of which may not exist, e.g. I have a line:-print day, fld[1], balance, fld[2] fld[2] doesn't always exist (fld is the result of a split) so the print fails when it isn't set.
What fails is the indexing operation. You can prevent that by slicing rather than indexing: fld[1:2], fld[2:3]. These will give '' if there is no fld[1], fld[2]. Whether or not this is sensible depends on what you want the output to look like in these cases.
