- Pickler(...)
- Pickler(file, protocol=0) -- Create a pickler.
This takes a file-like object for writing a pickle data stream.
The optional proto 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.
- Unpickler(...)
- Unpickler(file) -- Create an unpickler.
- dump(...)
- dump(obj, file, protocol=0) -- Write an object in pickle format to the given file.
See the Pickler docstring for the meaning of optional argument proto.
- dumps(...)
- dumps(obj, protocol=0) -- Return a string containing an object in pickle format.
See the Pickler docstring for the meaning of optional argument proto.
- load(...)
- load(file) -- Load a pickle from the given file
- loads(...)
- loads(string) -- Load a pickle from the given string
