For a large file, I'm not sure it is much faster to edit it in place than to rewrite it, and also since it's a large file, you are going to probably have it compressed, in which case you are out of luck anyway. > (of course it only works on a seekable stream ) Indeed... since I was dealing with zipped files, I had to pass in a "seek0" func, like so: file_in_seek0_func = lambda x: os.popen('zcat ' + file_in) _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
