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. Raises ------ EOFError If ``number`` is >0 and there are fewer than ``number`` objects in the pickled file. Returns ------- contents : object 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. rbTFr) isinstancestropencloserangeappendpickleloadEOFError) fileornamenumberfrresieofr]/var/www/html/bwave/python/venv/lib/python3.8/site-packages/astropy/io/misc/pickle_helpers.pyr s,    FcCs`|dkrtj}t|tr0t||r$dnd}d}n|}d}ztj|||dW5|rZ|XdS)aPickle 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 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).
