Even if that worked, it would be a long-winded way to do it. Please contemplate the docs: """getvalue( ) Retrieve the entire contents of the ``file'' at any time before the StringIO object's close() method is called.[snip note re mixing str & unicode] close( ) Free the memory buffer. """ The short working way is: """class StringIO( [buffer]) When a StringIO object is created, it can be initialized to an existing string by passing the string to the constructor.""" -- http://mail.python.org/mailman/listinfo/python-list
