Python StringIO Examples

Example #1

 def __init__(self, *args, **kw):
     self.__f = None
     if len(args) == 1 and isinstance(args[0], int):
         self.__f = StringIO()
         PythonPickler.__init__(self, self.__f, args[0], **kw)
     else:
         PythonPickler.__init__(self, *args, **kw)

Example #2

def dumps(obj, protocol=None):
    if protocol > HIGHEST_PROTOCOL:
        # use cPickle error message, not pickle.py one
        raise ValueError("pickle protocol %d asked for; "
                     "the highest available protocol is %d" % (
                     protocol, HIGHEST_PROTOCOL))
    file = StringIO()
    Pickler(file, protocol).dump(obj)
    return file.getvalue()
