Probably not, the StringIO solution is just closer to how you 
described the problem, but also provides a fuller set of file-like 
methods, including seek():

>>> import StringIO
>>> s = StringIO.StringIO()
>>> s.write('''
... here is some text
... that you can see''')
>>> s.read()   # at eof
''
>>> s.seek(0)
>>> s.read()   # at start of file
'\nhere is some text\nthat you can see'
>>>

HTH,
