\section{Standard Module \sectcode{StringIO}} \stmodindex{StringIO} This module implements a file-like class, \code{StringIO}, that reads and writes a string buffer (also known as {\em memory files}). 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.
