I agree that there may be circumstances where this naiive approach is sub-optimal. However, calling this careless programming is a bit over the top. Reading files into memory is often the preferred approach nowadays, and on a modern laptop (say) files several megabytes in size will be processed perfectly happily. Efficiency is good, but remember Kernighan and Plauger (elements of Programming Style): First, make it work. Then (if it doesn't work fast enough) make it work faster. Most times the simple solution works for the problem under consideration, and useless optimization work is avoided. regards Steve -- Steve Holden +44 150 684 7255 +1 800 494 3119 Holden Web LLC http://www.holdenweb.com/ -- http://mail.python.org/mailman/listinfo/python-list
