parameters: (self, file, protocol=None)
docstring: This takes a file-like object for writing a pickle data stream.
  
          The optional protocol argument tells the pickler to use the
          given protocol; supported protocols are 0, 1, 2.  The default
          protocol is 0, to be backwards compatible.  (Protocol 0 is the
          only protocol that can be written to a file opened in text
          mode and read back successfully.  When using a protocol higher
          than 0, make sure the file is opened in binary mode, both when
          pickling and unpickling.)
  
          Protocol 1 is more efficient than protocol 0; protocol 2 is
          more efficient than protocol 1.
  
          Specifying a negative protocol version selects the highest
          protocol version supported.  The higher the protocol used, the
          more recent the version of Python needed to read the pickle
          produced.
  
          The file parameter must have a write() method that accepts a single
          string argument.  It can thus be an open file object, a StringIO
          object, or any other custom object that meets this interface.
