Possible File Modes: a : Append -- Add data at the end of the file r : Read -- Read from the file w : write -- Flush contents of the file and put data in it r+ : read and write -- Make changes to the file any of the above modes with b added at the end of the mode sets the file in binary mode you might want to check section 7.2 from http://docs.python.org/tut/node9.html Ofen when doing file operations you might prefer to read the file to modify, make changes in memory then save back in an other file, so you can make sure the changes are ok before you replace the old one -- http://mail.python.org/mailman/listinfo/python-list
