I've sometimes replaced sys.stdout (and/or sys.stderr) to capture/redirect debugging information in existing code that has unwisely just "print"ed error and warning messages, instead of using sys.stderr or error logging modules. py> def with_output_to_string (func): ... try: ... sys.stdout = StringIO.StringIO () ... func () ... return sys.stdout.getvalue () ... finally: ... sys.stdout = sys.__stdout__ ... py> def printing_code (): ... print "Foobar" ... py> with_output_to_string (printing_code) 'Foobar\n' py> br, S -- http://mail.python.org/mailman/listinfo/python-list
