While that's generally true, it's worth noting that for small utility scripts of the "throw-away" variety, adding in the code necessary to do properly what Mike describes can make the difference between the code being quick and simple and (at least for those fairly new to Python) awkward and confusing, and thus potentially buggy. In my opinion, if the code fits on one screen and just reads stuff from one file and, maybe, writes to another, you can safely and with clean conscience ignore Mike's advice (but remember it for later!). -Peter -- http://mail.python.org/mailman/listinfo/python-list
