Parameters ---------- fileorname : str or file-like The file name or file from which to unpickle objects. If a file object, it should have been opened in binary mode. number : int If 0, a single object will be returned (the first in the file). If >0, this specifies the number of objects to be unpickled, and a list will be returned with exactly that many objects. If <0, all objects in the file will be unpickled and returned as a list. usecPickle : bool If True, the :mod:`cPickle` module is to be used in place of :mod:`pickle` (cPickle is faster). This only applies for python 2.x. Raises ------ EOFError If ``number`` is >0 and there are fewer than ``number`` objects in the pickled file. Returns ------- contents : obj or list If ``number`` is 0, this is a individual object - the first one unpickled from the file. Otherwise, it is a list of objects unpickled from the file. iNurb(RtPY2tcPickletpicklet isinstancet string_typestopentTruetFalseRtappendtloadtEOFErrortclose( t fileornametnumbert usecPickleRtfRtrestiteof((s=lib/python2.7/site-packages/astropy/io/misc/pickle_helpers.pyt fnunpickles2       cC`s¹|rtjrddl}n ddl}|dkrB|j}nt|tjƒrxt||rfdndƒ}t }n |}t }z|j ||d|ƒWd|r´|j ƒnXdS(u[Pickle an object to a specified file. Parameters ---------- object The python object to pickle. fileorname : str or file-like The filename or file into which the `object` should be pickled. If a file object, it should have been opened in binary mode. usecPickle : bool If True (default), the :mod:`cPickle` module is to be used in place of :mod:`pickle` (cPickle is faster). This only applies for python 2.x. protocol : int or None Pickle protocol to use - see the :mod:`pickle` module for details on these options. If None, the most recent protocol will be used. append : bool If True, the object is appended to the end of the file, otherwise the file will be overwritten (if a file object is given instead of a file name, this has no effect). iNuabuwbtprotocol( RRRRtNonetHIGHEST_PROTOCOLR R R R R tdumpR(tobjectRRRRRRR((s=lib/python2.7/site-packages/astropy/io/misc/pickle_helpers.pytfnpickleSs    N(t__doc__t __future__RRRRtexternRtextern.six.movesRt__all__R RRR R(((s=lib/python2.7/site-packages/astropy/io/misc/pickle_helpers.pyts " B
