StringIO
This module implements a file-like class, StringIO
,
that reads and writes a string buffer (also known as memory
files). See the description on file objects for operations.
When a 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 StringIO
will start empty.
The method getvalue()
can be called to retrieve the entire
contents of the ``file'' at any time before the StringIO
object's close()
method is called. Calling close()
will
free the memory buffer.
