How to Choose appropriate methods of 7-Zip encryption. Click theOptionsbutton that now displays in the Actions pane to set the encryption level. It does seem that the original file name has to include the path or the file can’t be found. The easiest way to do that is to drag the original file into the Terminal window after the ‘archivename.zip’ — Terminal will put in the path and file name. In snow leopard, the archive is created, but double clicking on it throws an Error 1 – Operation Not Permitted. (the “r” after the “-e” just means to also ZIP up any contents of a folder if you specify one; that’s necessary to ZIP up a folder—password or not—at least on Lion).

Unlike the DictReader class, the fieldnames parameter in DictWriter is not optional. Once we have an open file, we use the csv.reader() to parse the CSV file. It’s good to know that this reader will not read the entire file at once. It accepts any iterable object and starts requesting rows from the iterator.
