See the description on file objects for operations. When a \code{StringIO} object is created, it can be initialized to an existing string by passing the string to the constructor. If no string is given, the \code{StringIO} will start empty. The method \code{getvalue()} can be called to retrieve the entire contents of the file'' at any time before the \code{StringIO} object's \code{close()} method is called. Calling \code{close()} will free the memory buffer.
