You should use more consistent indents. Can you set your editor to automatically use four spaces each time you hit the tab key? In any case, you indent the "with" block. There are TWO lines indented, then you outdent again. That means the with block completes and the file is closed. You have: def test_restults(filename): ... with open(...) as f: indented block # f gets closed here for row in reader: indented block print result What you should have is: def test_restults(filename): ... with open(...) as f: indented block for row in reader: indented block # f gets closed here print result -- Steve -- https://mail.python.org/mailman/listinfo/python-list
